I have a usb wireless adapter, usb mouse and usb keyboard.. They were all working fine this morning but when i came back the wireless adapter and mouse stopped working, the mouse still gets power but doesn't move at all, i tried reinstalling drivers for both but no luck. I also can't find the devices in device manager.
I'm using windows XP home with sp2.
Also i have tried plugging in a flash drive which worked previously but now is not recognized.
