Hey! I've had my PC for a very long time (I use Windows XP) and everything seemed fine with it, until the "USB device not recognized" error kept popping up then disappearing after a few seconds all the time. So I tried: Unplugging my USB cables for my mouse,keyboard etc. then plugging them in, Updating and Rolling back my drivers,Powering off my computer from my power supply plug, but nothing is working!!! Sometimes it shows no device error, sometimes it's my mouse and an unknown device... Please help..
