Fix Unknown USB Device error message

If you aren’t able to pull up any website and instead got the ERR QUIC PROTOCOL ERROR error message in Google Chrome then read on as this post will help you resolve the problem. When you encounter such an error in Chrome, you will see the following error message:

“This site can’t be reached, The webpage at [website URL] might be temporarily down or it may have moved permanently to a new web address, ERR_QUIC_PROTOCOL_ERROR”

This kind of error message pops up when the URL is down. However, if you are certain that the site is not down and you’re still seeing this error message, then troubleshoot further using the suggestions given below.

Option 1 – Try to disable the QUIC Protocol

QUIC is an experimental transport layer network protocol that is present in Google Chrome in order to establish a connection between two endpoints over UDP. So if there is any problem on the development side, you will most likely encounter ERR_QUIC_PROTOCOL_ERROR on your Google Chrome browser when you try to open any website. Thus, you have to disable the QUIC protocol in order to resolve the error. How? Simply follow the steps below.

• Open your Google Chrome browser.
• Now type in “chrome://flags/” in the address bar and hit Enter.
• After that, look for the Experimental QUIC protocol which should be set by default.
• Then expand the drop-down menu and select Disable.
• Restart Google Chrome and see if the error is fixed or not.

Option 2 – Disable VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server to fix the ERR_QUIC_PROTOCOL_ERROR in Chrome. Refer to these steps to do so:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

What is Error Code 29?

Code 29 is a Device Manager error commonly seen whenever a hardware device driver reports a problem. This error code indicates that the resources needed for operation are not available.

The computer hardware basically requires drivers to interface with the operating system. Drivers comprise multiple components and are supplemented with other resources provided by the BIOS (a physical chip on the motherboard).

The BIOS contains a set of basic input and output instructions for the computer system to boot, load drivers, and more.

Its firmware provides resources that drivers require to interface with other essential components. However, when the firmware fails to provide the requested resources, the device drivers stop functioning; this results in error codes like code 29.

Error code 29 is usually displayed in the following format:

“This device is disabled because the firmware of the device did not give it the required resources” Code 29

Solution

Error Causes

Error code 29 may be triggered due to several reasons. These include:

• Outdated drivers
• Corrupted drivers

Ever gotten an e-mail offer that seemed just a little bit too good to be true? Might’ve been a phishing attempt! These are everywhere and can come in many different forms. 

So what’s phishing exactly, how can you detect it and how can you keep safe?

What is phishing?

Phishing (pronounced like fishing) is a type of cyberattack that tricks the user into trusting the source and revealing sensitive information. Fishing being the perfect analogy, the bait is a legitimate-looking site, e-mail or file and when you take a bite, your identity, banking information and much more can be revealed and stolen.

Some phishing attempts are incredibly obvious, others are super elaborate. Like with most types of malware, cybercriminals have become extremely well-versed in phishing and anyone can fall for it. To help you recognize and avoid it, we’ll take you through a couple of phishing types and give you tips on what to do if faced with them.

Phishing techniques

E-mail phishing

This is actually the most common type of phishing. A cybercriminal creates an e-mail containing stuff like attractive offers, legitimate-looking attachments or links and makes it appear as though it’s coming from a trusted source.

For example, it looks like it’s coming from your bank or your favorite retailer. The logo looks legit and the structure of the e-mail seems familiar, so you might get tricked into clicking on whatever clickable content is in it.

Unfortunately this exposes your device to malware that hands your data off to the hacker, who can decide what to do with it further.

SMS and social media phishing

Like the above example, you could be approached with lucrative offers or links via text messages or social media messages. Typically, the messages seem relevant to the user as they will be made to look like they’re related to apps or services you’re using.

Voice phishing

Voice phishing attacks are schemes that appear as though they’re coming from a credible number. Normally, you’ll get a call about something related to credit cards or taxes to get you into a state of worry, leading you to disclose personal information on the phone.

Spear phishing, whaling and BEC

Spear phishing normally targets specific individuals within a company who are likely to have access to sensitive data. Spear phishers spend time collecting information they can use to reach out to the individual looking as trustworthy as possible. They’ll typically lead with something relevant, for example mentioning an upcoming company event, and make a seemingly legitimate request.

Whaling is a more elaborate form of spear phishing, which targets people in even stronger positions such as executives or high-value individuals. The ultimate goal is to get them to transfer financial or other sensitive information that can be used to compromise the entire business.

BEC, or Business e-mail compromise, is a specific spear phishing technique carried out via e-mail. While there are many ways this is done, most commonly you’ll see instances where the phisher poses as a CEO or similar executive, or as a lower-level employee in specific positions (e.g. sales managers or financial controllers).

In the first situation, the impersonator reaches out to employees requesting them to transfer certain files or pay invoices. In the second situation, the phisher takes control of the employee’s e-mail account and sends false instructions to other employees in order to obtain data and information from them.

What can you do?

There are many ways you can be aware and spot a phishing attempt. Here are some tips:

• Always check the sender’s address in your e-mails, even when they seem to come from a familiar source.
• In any instance where payment information is requested, be very, very careful.
• If you are receiving attachments you never asked for and definitely didn’t expect, better not click on them. 
• Beware of content that transmits a sense of urgency (sales deals, urgent updates to login credentials, etc.).
• Bad spelling and grammar are usually a telltale sign of phishing.
• Links that look shortened (e.g. Bit.ly) or just suspicious in general - if you have a bad feeling, do not click on them.
• If you are receiving threats, you probably shouldn’t be clicking on anything in that message.
• Always examine first-time senders in detail.
• Block suspicious e-mail addresses, numbers and social media accounts.
• If you are receiving a coupon for free stuff… You aren’t.
• If you’re being asked to update your payment details by a service you use, such as Netflix, chances are it’s an impersonator.

Those are some of the ways to identify and prevent phishing attacks. However, sometimes phishers disguise themselves a little too well or a misclick happens and there you go - you’ve been exposed to malware.

This won’t happen if you invest in powerful protection software from the get-go, though. A good antivirus program like Bitdefender will keep you safe from becoming a victim of phishing scams. In fact, it will protect you from malicious attacks overall.

Be it your household or your business you’re concerned about, there are a bunch of different packages and options available, providing different kinds of cybersecurity services. That’s the only way you can ever really be sure you aren’t at risk of a digital attack.

Summary

Have you ever been targeted by phishers and didn’t know that’s what it was until you read this article? Many can relate. Protect yourself before it’s too late!

If you are trying to copy a folder or file in your Windows 10 computer but encountered an error that says, “There is insufficient disk space to complete operation”, then you’ve come to the right place as this post will walk you through how you can fix the error. This kind of problem could be due to lack of disk space, corrupted disk, and many more. In such cases, this error usually pops up when you move or copy a file or folder to a particular location. There are several potential fixes you can check out to fix this error. You can try to run the Storage Sense or Disk Cleanup or try copying or moving the file in a Clean Boot State. You could also try formatting the given partition to NTFS. For more information, refer to each one of the options provided below.

Option 1 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the “There is insufficient disk space to complete operation” error.

Option 2 – Restart your computer in a Clean Boot State

If the first options didn’t work and you still see the “There is insufficient disk space to complete operation” error when you copy folder or files, you can try putting your computer in a Clean Boot State and then again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect copy the folder or file once more and check if the error is now gone.

Option 3 – Try formatting the given partition to NTFS

Even though this option may take a lot of your time, it is proven to fix the “There is insufficient disk space to complete operation” error as reported by many users who also went through the same dilemma. So if the removable disk is showing the same error message no matter which computer you insert it, you might have to format the drive with the help of Command Prompt. But before you do that, you must know that all the contents of your drive will be permanently deleted after you format it.

• Tap Win + R to launch Run.
• Type in cmd and then tap Enter or click OK to open the Command Prompt.
• And in the elevated window of Command Prompt, type in the following command:

format F: /fs:ntfs

In the command given above, “F” is the drive letter and “NTFS” is the file system you want. Just remember to replace “F” with the drive letter you want to format as well as the file system you prefer. Brace yourself as this process might take quite a while even if you only have a 4 GB USB drive – so you must not close the window under any circumstances as the drive might get corrupted and wait for the process to finish.

If you are testing your headphone or your speaker but all of a sudden encountered an error that says, “Failed to play test tone” in your Windows 10 computer, worry not for this post will walk you through how you can fix this problem. The test tone is used to check the right-left balance of the headphones and speakers in your computer, however, if you are not able to use it, there are several options you can check out. You can try to run the Playing Audio troubleshooter or restart the services that are related to Windows Audio. Aside from these, you could also disable Audio Enhancements or you could also change the default test tone rate and bit depth.

Option 1 – Try to run the Playing Audio Troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to restart the Windows Audio-related services

The next thing you can do to fix the problem is to restart the services related to Windows Audio. Although the audio services start automatically on every system boot, there are times when they might fail to start. Thus, you can start these services manually by following these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Services Manager.
• Then look for the services named “Windows Audio” and “Windows Audio Endpoint Builder”.

You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 4 – Try changing the default test tone rate and bit depth

Windows selects a default test tone rate and bit depth depending on your headphone or speaker. This allows you to look for the best sound quality from your audio output device. So if your headphone or speaker has some problems with the default settings, then it’s no wonder why you’re getting the “Failed to play test tone” error. To fix this, you can try to change the default test tone rate and bit depth by following the steps below.

• First, you need to open the Windows Settings panel and then go to System > Sound.
• Next, look for the Device properties option located on your right-hand side and click on it.
• After that, select the Additional device properties option and go to the Advanced tab.
• From there, select a different test tone rate and bit depth and then click on the Test button.
• Once done, check if it was able to fix the problem or not.

Option 5 – Try disabling the Sound or Audio enhancements

To make your operating system’s specific hardware sound nothing but perfect, both Microsoft and third-party vendors have shipped audio enhancement packages which are usually referred to as “Audio Enhancements” in Windows 10. However, there are instances when instead of improving the sound or audio quality of your computer, it can cause problems so to fix the problem you need to turn off these audio enhancements. How? Simply follow the steps below.

• Type in “Sound” in the taskbar search and then from the list of results, select “Sound Control Panel”.
• After clicking Sound, the Sound properties box will pop up. From there, go to the Playback tab and right-click on the default device i.e. Speakers or Headphones then select Properties.
• After that, the Speakers properties box will appear. From there, go to the Enhancements tab and select the checkbox for the “Disable all enhancements” option.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try using Google Public DNS

If the first option didn’t resolve the issue, you can try to use the Public DNS by Google and see if it can help fix the problem. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 3 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the Err_Connection_Closed error. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 4 – Disable both the Antivirus program and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’re getting the “This webpage is not available, Err_Connection_Closed” error when trying to browse the internet.

Option 5 – Try to check the network cables and then restart your router

The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting this error.

Option 6 –Try a Network Reset

When all else fails, you might have to consider resetting your entire network settings. Simply follow the steps below to do so.

• Click on the Start button and then click on the gear-like icon for Settings to open it.
• Next, select Network and Internet.
• Then scroll down and look for “Network Reset” – click on it and then click on the Reset now button.
