I have a Toshiba Satellite A505 and have been using a wireless Logitech mouse/keyboard. Recently the laptop stopped recognizing the wireless usb instert, although it will recognize other usb flash drives. If I plug the Logitech mouse/keyboard usb into another computer the, the devices work fine. Also, the mose/keyboead usb instert does not not show up in the device manager, but the usb flash drives do. Any suggestions?
