My computer is unable to use one or more USB devices (such as a mouse, flash drive, external hard drive, etc...). How can this be fixed?
Skip this and contact a professional
There are multiple reasons this could be happening. As such, there are a few troubleshooting steps.
After each step in this guide, test the device again. If it begins work, you do not need to continue.
Try the USB device in a different USB port.
The troublesome device should also be checked in another PC. If it doesn't operate with the other PC, it's likely a problem with the device itself. In that case, the device is at fault rather than the computer, and you should contact the device manufacturer. If it's a Toshiba accessory, you can make a warranty claim or call customer support.
Power Management and USB Controller
Uninstall and Reinstall the USB Controller
Safe Mode / Clean Boot
Contact Customer Support, Make a Warranty Claim, or Seek Servicing
If none of these suggestions work, you may have a hardware failure of some sort.
If the problem is with a single accessory, contact that accessory's manufacturer if the manufacturer is not Toshiba or make a warranty claim if it is a Toshiba product.
If the problem is with multiple USB devices and your computer is in warranty, please contact Toshiba customer support. Otherwise, if you'd like to contact a professional, CLICK HERE.
