This solution has worked for some people with problematic USB devices:
Locate the file INFCACHE.1 in C:\Windows\inf
Right click on the INFCACHE.1 file, select Properties >Security > Edit, and give
your account full control.
Delete INFCACHE.1, or rename it to INFCACHE.1.BAK or temporarily move to your
desktop.
REBOOT
If this works for you, you can delete the INFCACHE.1 file. Windows will not
recreate it.
