The USB–C connector has been on the market for some time. So why is it still so hard to find a great USB–C hub?What is USB–C?
USB Type C, or USB–C to its friends, is the newest USB connector standard. It replaces all the USB connectors that came before it, so it supersedes all the Mini and Micro cables of older standards. USB–C also supports the highest data and power transfer rates of the USB 3.1 Gen 2 standard, cranking up as high as 10 Gbps and 100 watts. It’s the most robust, durable, and powerful USB connector type available.
USB–C should not be confused with the USB 3.1 specification; USB–C is simply a connector type. Cables and devices with USB–C connectors can support data transfer rates from USB 2.0’s 480 Mbit/s to Thunderbolt 3’s 20 Gbps. Fortunately, all cables with USB–C connectors must contain a chip reporting what kind of speed and power they can safely handle.
It might be less obvious to consumers. You need to shop carefully and look for the specific logos stamped on the cable end. Look for the USB 3.1 Gen 2 Superspeed trident with the 10 Gbps branding.Challenges for USB–C
So if USB–C is the biggest, baddest new USB connection standard, why isn’t it better supported by the marketplace? Mostly, it comes down to a much smaller market, lack of competition, and OEMs’ relative inexperience with the USB 3.1 standard.1. It’s still new
In addition to its new power, USB–C is the newest connector type on the market. While you’ll find it on some devices, very few computers offer solely USB–C ports. Apple’s MacBook and MacBook Pro are the notable exceptions, although the USB–C connectors on those computers actually might support Thunderbolt 3, depending on the model. The connector type has begun its slow diffusion through the peripheral market, but it hasn’t made much of a dent yet.
But replacing a connector as popular and widely used as USB is bound to take a long time. That kind of change doesn’t happen quickly. So adoption of Type C was always going to be more of a trickle than a flood: a few devices at first, starting with speed-sensitive applications. Eventually, Type C will take over completely, but it’s hard to predict when that day will come. Right now, that day seems distant.2. Demand is low
This limited adoption means that there’s not yet a huge demand for USB–C devices. Since few devices support the standard, most folks haven’t really caught on yet. And when they do purchase a device with USB–C, they’re likely to buy a conversion dongle to continue using the USB Type A connectors on their computer. Simple direct conversion dongles for USB–C to USB A are also reliable and cheap, so it’s a good choice for most users. Thanks to the relatively slow uptake of USB–C among consumers, there isn’t as much competition in the market for hubs and cables.3. Lack of manufacturing expertise
Because relatively fewer hubs are being made, manufacturers don’t get as much practice to iron out the defects in their design and production processes. That means the hubs are more likely to be unreliable or not fully up to spec in ways both frustrating and limiting. While your host device will likely “see” the USB ports and recognize devices connected to them, the connection might be buggy or slower than necessary.
Just multiplying USB–C ports is actually the easiest way to make a USB–C hub. However, even that is more complicated than USB 2 thanks to changes in the standards. But it’s not as difficult as making a multi-input USB–C hub. And that’s just what many manufacturers are trying to put out. It’s the big appeal of USB–C, after all!
USB–C’s “alternate modes” can take graphic or network input, and those ports are even more likely to be buggy. That’s one of the reasons that USB breakout hubs are so expensive: they’re harder to design and build. Since data type is no longer segregated by connector, the USB–C hub will include some chipsets to sort out inputs. And all that’s not necessarily a straightforward process. The majority of factories in China, where nearly all hubs are built, are great at cheap, straightforward processes; other things need practice and expertise.
It’s not just hubs; cables aren’t even safe. Stories about out-of-spec USB–C cables frying laptops are not unheard of. As OEMs gain experience, this will become less of an issue. But for now, it’s a real concern.What to Buy?
As time goes on, all these problems will lessen and eventually disappear. As fabricators get better at building USB 3.1 Gen 2-compliant hardware, we’ll see a commensurate improvement in the quality of hubs available. Until then, reviews are your friend. Look for devices made by reliable manufacturers with positive reviews from real users.

Yes, there is no goto statement in Python. Let us first understand what is a goto in C Language. However, the usage of goto is also discouraged in C.
The goto statement in C programming provides an unconditional jump from the ‘goto’ to a labelled statement in the same function. Following is the syntax −goto label; .. . label: statement; Example
Let us now see a C program for goto −
“a = %dn”
}Output a = 10 a = 11 a = 12 a = 13 a = 14 a = 16 a = 17 a = 18 a = 19
NOTE − The use of goto statement is highly discouraged in C language as well.No GoTo in Python
In Python, there’s no need of goto since we can accomplish the same with if statements and or, and, and if-else expressions & loop with while and for statements, containing continue and break.User-defined Exceptions
Use user-defined exceptions as an alternative −
)Nested Methods Example
Use nested methods as another alternative −
“In the demo() function”
)Output In In the demo() function The goto-statement module
It is a function decorator to use goto in Python. Tested on Python 2.6 through 3.6 and PyPy. Install it using the pip −
Note: Works till Python 3.6pip install goto-statement
Let us see an example −
Understanding that no two SEO campaigns are the same is a challenge in getting wider business buy-in to the project.
One example that sticks out in my mind is working with a global travel company who was comparing their website and infrastructure with that of BBC News.
“The BBC doesn’t do it that way,” was a common phrase thrown into the mix.
Having worked with a number of organizations, ranging in size from sole traders to IPO SaaS companies, one thing is apparent.
While SEO best practices may be a consistent benchmark to aim for, no two successful SEO strategies are the same – even if two websites are in the same vertical.
When we look at “ranking factors” or things to move the needle in favor of our client’s websites, there are a large number of factors that need to be taken into account including:
The tech stack your website is running.
The lead time from a development request being made to deployment on production.
How much investment has been made/has been planned into brand building and general PR.
How much resource is available to produce content (internally and externally).
The level of competition for the target topics and search phrases.
The end goal of users on the website (product sale, lead generation, article view).
All of these factors are dependent on the business and the business model.
And, unless you have inside information, it’s highly unlikely that you can answer the same points for your competitors as you can for yourself.
This is why there is a lot of debate within the SEO industry about pretty much anything to do with SEO.
A prime example being the ongoing debate around just how valuable inbound links are in terms of the wider mix. In some verticals and for some websites, they’re a lot more important than others.
This is because as SEO professionals, we’re all exposed to varying levels of challenge.Industry ‘Ranking Factors’
In the past, Searchmetrics has produced a ranking factor study looking at “universal ranking factors”, as well as weighting them by industry – to show the differences between them.
Comparing the Travel Industry and the Finance Industry from the study, top factors that correlated with higher performance within organic search were:
Page word count is higher.
Number of bullets user per list.
Number of internal links.
Number of images used.
In comparison to the top correlating factors in the Finance Industry being:
Content relevance and core topic.
File size and page load time.
The number of AdSense/AdLinks (less is more).
So does this mean that internal linking structures aren’t important in the Finance Industry and shouldn’t be a key part of your SEO strategy?
No, it doesn’t.
While studies like this are great, they only cover quantifiable elements that can be easily measured across a large sample of websites.
They don’t take into account more objective and subjective factors, such as brand and offline presence.
These do however show the different approach taking in each vertical, and this is majorly influenced by business model and product type.
You’d expect a travel website to contain a large number of images and contain lots of guides talking about destinations with persuasive copy.
Whereas from a financial website or bank, you’d expect non-verbose copy that’s straight to the point with the information the user needs.Some Things Are Universal
Correlating factors aside, some elements of organic search (within Google) are universal and should really be seen as basics across all websites, with strategy then being overlaid on top. These are:Site Speed
Important for SEO and site usability. Not so much a problem today, given the increased spotlight that Google gave site speed in previous years, making it a staple part of the SEO auditing process.
The majority of websites also now run behind CDNs that allow for things such as JS/CSS and HTML compression.
It’s also important to consider the differences between the HTML response and the rendered response, and have a non-JS fallback solution in place if possible as this can affect:
New URL discovery.
New URL indexing.Machine Learning & the Web Corpus
Whenever I’m talking about comparing two or more websites, I refer back to a Moz Whiteboard Friday from 2023. It looks at how Google may (or may not) interpret and evaluate the value of your content in comparison to the wider web corpus.
Although the video and transcript don’t directly mention machine learning and Google’s artificial intelligence, Rand Fishkin did talk about how Google assesses the web corpus and takes learnings from it – using the example of granola bars.
This is were approaches and strategies between competing websites tend to overlap.
In the example, when Google is assessing the quality of a page talking about granola bars, it’s looking at the web corpus for information and typically, you’d find pages containing nutritional value tables and lists of ingredients and allergens.
From this, they would see keywords such as [calories], [fats], [sugars], and then differentiating keywords such as [organic] and [vegan].
Applying this to another vertical such as travel, a page targeting [italy tours] may also talk about [rome coliseum], [milan], [venice], or [pompeii].
If Google finds 100 websites with a page targeting [italy tours], and 87 of the 100 contain a group of related topics and keywords and 13 don’t, machine learning (and logic) will go with the more consistent corpus.
This is also when you break away from just looking at single pages in silo, and start looking at:
The main content/supporting content elements across the domain.
Internal linking that creates little microsites of user value around a topic with content addressing multiple user intents (i.e., commercial pages, evergreen guides, and the blog).
Because Google is aware of what the web corpus is saying, you need to be in line with this and then develop the strategy to go one better – not just mirror what Google already sees as being rank worthy.Optimizing for Your Business Model
It’s important that you use the right strategies for your business model and target user base – taking into consideration your competitive space.
While some technical elements of SEO are universal, it’s not possible to blindly imitate strategies between websites and expect the same results.
This is why it’s difficult to forecast the impact of specific SEO tasks.
Due to the sheer number of variables (internal and external), no two websites are “the same”.
Saying that a website is “similar” is not enough.

I had sporadically seen mysterious nitrogen canisters on New York City sidewalks, and wondered what they were doing there. Each tank has a hose snaking its way into a manhole, where it presumably dispenses nitrogen under the street. Luckily, Popular Science let me find out as part of my job (booyah). It turns out they’re there to keep copper cables dry so phone and internet services can run smoothly.
Verizon spokesman John Bonomo said the tanks supplement the company’s existing pressurized system to keep its cables dry when repairs are going on or there’s too much steam present. The cables have a protective sheath around them, but sometimes it’s not enough to keep them dry. “But as durable as that is,” Bonomo said, “that gets penetrated by the elements, as well, over time.”
As the liquid nitrogen leaves the canister, it turns into a gas. When nitrogen undergoes this phase change, it expands 175 times. This keeps the cables at a high enough pressure to keep moisture out.
Two tanks at Madison Avenue and East 27th Street in Manhattan have been there for about a year because of steam buildup, said Verizon’s local manager for Manhattan pressure Alex Diachok. The space under Madison and Lexington avenues, especially, is much smaller than other areas under the city, he said, and temperatures can reach 220°F. The tanks are mostly used in Manhattan because of the congestion, temperature and water table of the island, Bonomo said. Dan Mattiace from McKinney Welding Supply, who supplies Verizon’s nitrogen, said liquid nitrogen is the best option for this application because liquid oxygen is combustible, and liquid helium and carbon dioxide are too expensive.

While the warning signs on the tanks may seem alarming, Bonomo said they have never exploded or significantly leaked in the city, but they have tipped over on occasion when a car has backed into them, for instance. The cans are so sturdy that toppling hasn’t caused any leaks, Diachok said, and Verizon technicians are able to simply stand them back up. Sometimes the tanks need to release pressure by shooting a plume of nitrogen above the tank. It looks like snow because the nitrogen cools the water molecules in the air so quickly that they freeze. Verizon area manager for insulation and maintenance Patrick Johnson said this is just a normal function of the canisters and is nothing to worry about. Verizon technicians check each canister every night to make sure they’re functioning properly, Diachok said.
“We’ve done a lot of work to get these off the street,” Johnson said. “It’s a big expense. This is not our business.” Just refilling the tank costs about $100, Diachok said, which they have to do every day to every three days. Right now in the city, Verizon has 54 tanks at 28 sites, and that number goes up in the winter when there’s more steam underground since it’s used to heat the buildings.
Verizon’s copper cables mostly send phone calls, but also transmit fire and security alarms and still carry some internet via DSL, too. As Verizon transitions its network from copper cables to fiber, the nitrogen canisters will go away, since fiber-optic cables are impervious to water.

There is no “simple trick” to privacy
As 2023 draws to a close, if the past twelve months – indeed, the past decade – have taught us anything, it’s that you can’t take privacy for granted. While there have been plenty of high-profile hacks, leaks, and data exposed through general mismanagement by companies large and small, the reality is that much of the time our personal information gets distributed not because it’s stolen, but because we don’t take sufficient care with it.
Already we’re looking to close out 2023 with another corporate confession of misappropriated data. Security camera company Wyze is behind the latest mea-culpa in our inbox, admitting that its databases were exposed for a time, and accessed by an unknown third party.
Wyze, though, is by no means the only company that has discovered, to its embarrassment, that its ability to secure the data its customers share is far less impressive than its ability to collect it in the first place. Certainly, the fact that the company is in the security field makes the irony more stinging. Yet far bigger companies than the connected camera and alarm startup have had to come, cap in hand, and tell its users that a screw-up has occurred.
Embarrassment, though, is arguably an insufficient motivator for meaningful change. If there’s one thing companies understand – and quickly – it’s impact that affects their bottom line. There, though, we’re not living up to our end of the bargain.
Take Facebook, for example. Its track record over the past decade when it comes to handling your personal information has been dire, frankly. Investigative attention from regulators has forced it, seemingly grudgingly, to massage its privacy policies and the ways in which it uses our data, but it’s hard to escape the feeling that this is the digital equivalent of closing the stable door after the horse has bolted.
Facebook growth-hacked its way to dominance, for instance, by using the phone number you provided for extra security to encourage more people to add you as their friend. Now it won’t do that any more, which is good, but the damage is already done. And I’m not sure that it would ever have stopped misusing two-factor authentication numbers in that way, had it not suddenly found itself under the microscope for privacy mismanagement.
Companies – and hackers – have already figured out that personal data is arguably the most valuable currency out there today. Adages like “if you’re not paying for it, you’re the product” may be commonly quoted, but there’s little indication that we’re taking the sentiment to heart. Sure, there are meaningful barriers like privacy agreements dripping in legalese and a dozen pages long, but even so; it’s tough to argue that most of us are doing our due-diligence.
Today, with likely hundreds of thousands of smart speakers freshly installed in homes across the world after Amazon, Google, and others pushed them so eagerly over the holidays, it’s easy to assume that tapping the microphone-mute button or sliding a camera shutter is enough to secure your privacy. Yet the reality is that, while you could well argue it’s not sensible to bring an always-on microphone into your home, any feeling of wellbeing from knowing that Alexa, the Google Assistant, or whichever other AI isn’t listening to you is outweighed by the rest of the data you’re freely sharing every time you go online.
There are signs that changes are afoot. You may have noticed an uptick in emails landing in your inbox, from companies notifying you that they’ve updated their privacy policies. That’s down to the imminent arrival of the California Consumer Privacy Act (CCPA), which comes into force on January 1st.
The CCPA won’t change what data companies can collect about you: they’ll still be able to gather up as much as you’ll willingly give them. What it changes, though, is user access to that data. Those in California will be able to find out what personal data a company has saved on them, access it, request it be deleted (with a few security-minded exceptions), and not only discover if it has been sold or disclosed, but deny permission for such a sale.
Though it’ll be the toughest consumer privacy law in the US, it’s still not perfect. The CCPA only covers information shared by the consumer; if a company purchases data, or gathers it from publicly-available sources, the law doesn’t apply. A business needs to be either large (with gross annual revenues above $25 million) or deal significantly with personal information (either buying or selling the data on 50,000 or more consumers or households, or earning more than half its annual revenue from the sale of such information) to be subject to the new rules.
Other limits fall around the repercussions of contravening CCPA. If a company doing business in California is subject to a data breach, and can’t demonstrate it had maintained “reasonable security procedures and practices,” it can be fined and the target of class action lawsuits. However there’s no explicit punishment for companies that sell data even if they’re told by a user not to.
CCPA, in theory, only impacts the state of California. However several big companies are adopting its mandates nationwide – including Microsoft – even as others protest what they claim is a lack of clarity from the law’s authors. Even if rule-breakers persist, it’ll be down to organizations like the office of California’s Attorney General to actually step up and enforce the CCPA’s requirements. It’s unclear whether federal legislators have the appetite to roll out a US-wide version.
And there, again, we come to individual responsibilities, the counterpart to our digital rights. Rules like the CCPA may outline our expectations from the companies we entrust with our digital lives, but all the transparency in the world about privacy policies and access to records are for naught if we don’t actually read them. The CCPA might force disclosure of data being collected, but that’s only useful if we ourselves read that disclosure, and make balanced decisions about who we’ll then share that data with.
In short, there’s no “simple trick” to ensuring privacy and the security of your personal information. Even starting out 2023 by deleting your Facebook account won’t be enough to keep “safe” online. Rules like the CCPA and the proposed Online Privacy Act may end up giving us the tools to control how our information is shared and monetized, but that’s only if we acknowledge that there’s no quick fix to taking care of our most important data.
In this article, we will talk about what you should do if USB ports are not working on your PC. USB ports on a computer allow users to connect different USB devices, like printers, keyboards, mice, etc. If the USB ports stop working, you will not be able to use any USB device. USB ports may stop working due to hardware and software issues.USB ports are not working in Windows 11/10
A USB port stops working if it is faulty or if its drivers are outdated or corrupted. Sometimes, the latest Windows Update causes issues on a computer. In addition to the hardware and software issues, a USB port may also stop working if you quickly and repeatedly insert and remove a USB device. This article provides some helpful suggestions that you can follow if your USB ports are not working.
Power Cycle your computer
Check the power output of USB ports
Run Hardware and Devices Troubleshooter
Disable Fast Startup
Scan for Hardware Changes in the Device Manager
Roll Back, or reinstall USB Controllers
Change the Power Management settings
Uninstall and reinstall the USB Root Hub
Update your chipset driver
Disable the Selective Suspend feature of Windows
Uninstall the recent Windows Update
Restore your system
Perform an In-place Upgrade
Let’s see all these fixes in detail.1] Power Cycle your computer
The first step that you should do is to power cycle your computer. The following steps will help you with that:
Turn off your PC.
Remove all the power cords. If you have a laptop, remove its battery after turning it off, and then remove all power cords.
Wait for a few minutes.
Laptop users can now insert the battery again.
Reconnect all the power cords.
Turn on your computer.
Now, check if the issue is fixed.2] Check the power output of USB ports
Most USB ports supply 5V of electricity with a maximum current of 0.5 A. If your USB ports are working, they supply power output. If a USB port is not supplying power, it may be damaged. Check the power output of your USB ports to know if they are damaged or not.
If your USB ports are not supplying power, you need to take your computer to the service center.3] Run Hardware and Devices Troubleshooter
The Hardware and Devices Troubleshooter helps Windows users fix hardware-related issues (if possible). In the previous step, if you find that your USB ports are not supplying power, run Hardware and Devices Troubleshooter before taking your laptop or desktop computer to the service center.
Fix: Generic USB Hub missing or not showing in Windows4] Disable Fast Startup
Fast Startup allows your computer to start faster than a normal startup. The Fast Startup does not completely shut down your computer. During the Fast Startup, the kernel session is not closed. Instead, it is hibernated. Windows does this by saving the kernel session and the device drivers (system information) to the hibernate file (hiberfil.sys). Due to this, sometimes, Fast Startup causes issues on a Windows computer. Check if the Fast Startup is enabled. If yes, disable it and restart your computer.
There are the following 4 ways to disable Fast Startup. You can use any of these methods.
The Control Panel
Group Policy Editor (does not work on Windows 11/10 Home edition)
Registry Editor5] Scan for Hardware Changes in the Device Manager
Some users have reported that the USB ports of their systems were delivering power but there was no connection. If this is the case with you, scan for hardware changes in the Device Manager. It will help.
Follow the steps written below:
Open the Device Manager.
The above action will help broken devices work again. Now, check if the issue is fixed.
Read: How to enable or disable CD/DVD ROM Drives, USB Drives or Ports in Windows6] Roll Back, or reinstall USB Controllers
A USB Controller manages the communication between a USB device and a computer. If the USB Controller gets corrupted, the USB ports may stop working. If the issue still persists, we suggest you roll back or reinstall the USB Controller driver.
Installing Windows Update also updates the device drivers (if an update for the same is available). If the issue started occurring after a Windows Update, it is possible that the USB Controller driver was also updated along with the Windows Update. In this case, the Roll Back option will be available in the Device Manager. Follow the steps below:
Open the Device Manager.
Expand the Universal Serial Bus controllers branch.7] Change the Power Management settings
If you are still facing the problem, changing the Power Management settings of the USB Root HUB and USB Controllers will fix the issue. The steps for the same are written below:
Open the Device Manager.
Expand the Universal Serial Bus Controllers node.
Open the properties of USB Host Controllers and go to the Power Management tab.
Uncheck the “Allow the computer to turn off this device to save power” option.
Disable this option for all USB Controllers and USB Root Hubs in the Device Manager. When this option is enabled, Windows disables the USB devices after some time of inactivity to save power. When you use that device, Windows activates that USB device again. Sometimes, Windows fails to activate the device connected to a particular USB port due to which, it seems that the USB port has stopped working.
Read: USB-C not working, charging or recognized on Windows8] Uninstall and reinstall the USB Root Hub 9] Update your chipset driver
A chipset driver tells Windows how to communicate with the motherboard and small subsystems on it. One possible cause of this issue is the corrupted chipset driver. Update your chipset driver and see if it helps.10] Disable Selective Suspend
Selective Suspend is a property by which Windows forces the connected USB device(s) to enter into a low power state. This happens when there is no bus activity on a particular USB port detected for some time. When you use your USB device, it starts working again. The purpose of Selective Suspend is to save power. If the above fixes did not resolve your issue, you need to disable the Selective Suspend feature. This action will affect all the USB host controllers and all the USB devices. After disabling Selective Suspend, all the USB devices continue to use power. Moreover, the “Allow the computer to turn off this device to save power” checkbox may be greyed out under the Power Management tab.
To disable Selective Suspend, you have to modify your Registry. Be careful while modifying the Registry, as any mistake can lead to serious errors in your system. Therefore, follow the steps explained below carefully and make sure that you modify or change the right registry key.
Before you proceed, we recommend you create a System Restore Point and backup your Registry.HKEY_LOCAL_MACHINESystemCurrentControlSetServicesUSB
Read: Free USB Repair Tools for Windows 11/10 PC.11] Uninstall the recent Windows Update
If your system’s USB ports stopped working after installing a Windows Update, you can uninstall that update. Windows 10 users can uninstall Windows Update via the Control Panel. After Windows 11 2023 Update, it is not possible to uninstall the Windows Updates via the Control Panel. Hence, you have to use the Settings app for this purpose.12] Restore your system
You can use the System Restore tool to take your system to the state before the issue started occurring. But this is only possible if a Restore Point was created. When you run the System Restore tool to restore your system, Windows shows you all the restore points created on your device along with the date. You can select any of these restore points. In your case, you have to select that restore point that was created before the issue started occurring.13] Perform an In-place Upgrade
In-place Upgrade is the process of installing the Windows operating system over the existing Windows OS without uninstalling it. Using the In-place Upgrade, you can repair your system. Though an In-place Upgrade does not erase data, it will be good if you back up your data.
Read: USB 3.0 External Hard Drive not recognized in Windows.How do I get Windows 11 to recognize my USB device?
If Windows 11 is not recognizing your USB device, the first thing that you should do is restart your computer and see if it helps. In addition, the other things that you can do to get your USB ports to work again are running Hardware and Devices Troubleshooter, disabling Fast Startup, rolling back or reinstalling the USB Controllers, updating the chipset driver, disabling the Selective Suspend feature, etc. In this article, we have explained some working solutions to fix this problem.Why do my USB ports suddenly stop working?
Quickly and repeatedly inserting and removing a USB device can make a USB port unresponsive. When a USB port is in this state, it doesn’t recognize the connected USB device due to which the USB device does not work. Other causes of this issue are the Selective Suspend feature of Windows, corrupted or outdated USB and chipset drivers, corrupted system files, damaged hardware, etc. Refer to the solutions explained in this article to know how to fix this problem.
I hope the solutions provided in this post helped you fix the issue.
