Hi, for almost a week now, my computer no longer sees devices connected on the USB port. I have attached my phone, camera, drives, etc., but nothing seems to work. Is it a virus? How do I reset the USB of my computer? I can use the other ports, but I need all to work. Thanks.
Today, we will talk about an issue most people have experienced on their computer USB ports (including the USB port for headphones, camera, USB flash drive, etc.), where it suddenly stops recognizing plugged-in devices. The tricky thing about reset USB is that a variety of factors could potentially lead to your USB drive not working, and it can be solved by methods ranging from simply blowing out or removing obstructions from the port or having to reset it completely.
Here is everything you need to know about this situation and several proven methods of performing a reset on USB ports no matter with or without physically disconnecting/connecting from the PC.
Before doing anything technical, you should first confirm that nothing is blocking the USB port. Most times, debris can obstruct the contact between the connector and port. So, your first step here is to shut down the computer and remove any obstruction with a thin object like a toothpick or blow it out.
USB ports may also not work if there is a partial connection in the port. If there is no obstruction, you can put on your computer, connect the USB, and wiggle the connection gently.
On electronics, sometimes a restart fixes minor issues, and this is also true for USB not working. After inspecting the ports, if your computer still does not see your connected USB device, restart the system and hopefully, the PC fixes itself. If it doesn’t, continue to the next method.
You might not be aware of this, but Windows disables some unused USB controllers automatically to conserve power. However, you know, no matter how smart the computer is, it’s still basically a machine and is prone to errors and miscalculations. Sometimes, these disabled controllers do not come back on when in use, and this could lead to USB not working. If restarting your computer does not work, follow the steps below to prevent Windows from deactivating USB controllers at all:
Step 1. Launch “Device Manager”.
Step 2. Click the dropdown on “Universal Serial Bus controllers” to expand the branch.
Step 3. Double-click on the first device in the list and click “Power Management”.
Step 4. Make sure the “Allow the computer to turn off this device to save power” check box is left unmarked. Click “OK”.
Step 5. Repeat step three and four on every USB Root Hub device in the list.
Thanks to some errors, the USB port controller driver may have been corrupted or missing. If the previous solution does not work, try re-enabling your USB controller from Device Manager. I’ll show you how.
Press the Windows key + R, and the Run box will open.
Enter “devmgmt.msc” and hit Enter to open “Device Manager”.
On the list, locate “Universal Serial Bus Controller”.
Click on the little dropdown next to the option to reveal all the controllers.
Right-click on a USB controller on the list and click “uninstall”. Repeat this for all the USB controllers on the list.
Reboot your computer.
If the driver had a problem, Windows would reinstall it on booting your computer, and your USB will work fine.
Step 1. Open “File Explorer” and enter 'troubleshoot'. Click “Troubleshooting”.
Step 2. Navigate to “Hardware and Sound > Hardware and Devices. Next, click “Advanced” and tick “Apply repairs automatically”. Hit “Next”.
Step 3. The program now starts to find and resolve existing issues in your drive. Click “Apply” and then hit “Next” to continue.
Step 4. Next, select “Enable” and close the “Troubleshooter”.
Step 5. Restart your computer to effect the changes.
