USB problem

I just picked up An ASUS CM 6850, i7,8g , 1T on E-Bay, runs great, funny thing though ,just checked Device Manager and on "other devices" it shows a USN contoller with no driver, yet under
"USB devices" they all show good and the usb drives work. Any ideas? T.I.A.

 

Try installing the wireless USB drivers if they're available,in fact I'd install all the latest drivers as a matter of course.

I'd link you but you haven't supplied your operating system.

Try to uninstall all the drivers related to your Flash Drive and then reinstall the correct one. With so many drivers installed on your system, you cannot reasonably keep track of which driver has been updated.
