Hi,

Did you guys meet such a problem? When you access to an external USB hard drive, it says an error message:

USB Device not recognized: One of the devices attached to this computer has malfunctioned and windows does not recognize it

Is there something wrong with the USB device? Or does it mean something wrong with PC?

I have tried many times. How can I fix it? Thanks.

This issue can be caused by any of the following situations:

1. The currently loaded USB driver has become unstable or corrupt
2. Your PC requires an update for issues that may conflict with a USB external hard drive and Windows
3. Windows may be missing other important updates hardware or software issues
4. Your USB controllers may have become unstable or corrupt
5. Your external drive may be entering selective suspend
6. Your PC motherboard may need updated drivers.

Try to check if the situations exist and fix it.

Hi mirs, thanks for help. I have fixed it!

Did you have to delete the USB drivers from Device Manager and have Win 8 CP reinstall them or something else. The fix is important so others may know in case they have similar problems.
