Okay i was playing Starcraft 2 and all the sudden they stopped so i restarted my computer and they still don't. I don't know what happened, the usb gives off power and reads the device in it it just wont work. For instance it can read it when i plug more than 1 mouse in my computer but it wont work. I have tried just about everything, except reinstalling my OS, updating my bios ( I don't see why though cuz it has worked for me for over 2 years). I have uninstalled the drivers from the device manager, disabled and enabled them, and i checked to see if the setting in my bios are enabled and yes they are any more suggestions. O and a old p2 keyboard i have works just my usbs dont.
