Recently my USB keyboard and mouse has been stopping working randomly every once in a while, and only working again after I restart my laptop. Putting them in different usb slots doesn't help, and other devices like mp3 players still work in the same usb slot. Tried using another mouse, still didn't work, but the original one worked on a different laptop. I can't see a pattern in when they stop working, and there's no recurring events.
I have windows 7, mouse is a wired optical Logitech, keyboard is a simple wired microsoft one. I have updated and uninstalled and re-installed the drivers, ran anti-virus and malware scans, and it hasn't helped. Any ideas?
