I have an HP DV7t laptop running Windows Vista 64 Home Premium that suddenly won't "see" any USB flash drives (all the drives work fine on other PCs). When I plug one in, nothing happens. You hear the USB sound but AutoPlay doesn’t run and when you look in "Computer" in the Start Menu you don’t see the drive.
The flash drive shows up in Disk Manager but doesn't have a drive letter assignment and you can't assign one. It does show up in "Safely Remove Hardware" as a normal flash drive with the correct drive name, ie, "Corsair Flash Voyager", and you can stop and remove the drive as if it were functioning normally.
I've tried deleting drivers, USB entries in Device Manager, etc., and then rebooting, but Vista always comes back with "Windows couldn't find driver software for your device". I have attempted many other solutions as well but nothing seems to work. All Windows Updates have been applied & malware scans come up clean.
From Google searches I see that this is apparently a common issue with Vista
...Does anyone know how to fix it?
