Hello, I have the P7P55D mobo and the rear usb ports, ALL of them do not work with some devices. I get Code 10 in devman, device cannot start in windows 7 pro 64. Am I missing something here? Devices I have issues with is my Tritton AXPC Pro headset and a Logitech G15 Keyboard. They work ONLY on the front ports and if I have them both connected the mic doesn't work or the mic works and typing doesn't LOL, very odd. All my other devices work fine on those USB ports. Need some help here
