Question : Problem: USB device not recognized - unknow device

I bought a logitech LX7 wireless mouse.
When I plug it in my USB ports get messed up after a while and some times immediately.
The error message is USB device not recognized and unknown device in device manager.
I have external hard drives and a usb hub that have worked perfectly and still do until I plug in the mouse and then everything doesn't work.
I have followed other solutions that solve the problem for my other devices but when I try to plug in the mouse, everything gets messed up again.

Answer : Problem: USB device not recognized - unknow device

here some things to try :
unplug pc from power for 30 minutes
then test
-----------------------
See if the following registry key exists
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\Vid_0000&Pid_0000
delete the Vid_0000&Pid_0000 key
reconnect the suspect device
refresh (f5)
if this key reappears then the device is U/S
----------------------
 copy the USBSTOR.SYS from a working PC to the bad one. (copy the old one somewhere else first)
normally located at c:\windows\system32\drivers
