Hi there, I have 2 USB ports on the front panel of my PC. One is completely dead, nothing happens at all when a device is plugged in ie a joystick, camera, ipod etc. The other port is malfunctioning, for example when i plug a joystick in it makes the little 'beep' which you would expect, and in the control panel/game contollers list, the joystick momentarily appears, but then disappears after a couple of seconds. I've gone into device manager, and checked the USB Root Hub properties, which recognises the Logitech joystick as present and requiring 30mA, (with 500 available). The USB ports at the rear of the PC which are on a PCI card are working fine. I'm running WinXP sp2. Any thoughts?
