- USB mouse and keypad now return NAK response when idle and there is no change. - Implemented HID commands for get/set idle duration. - Fixed NAK behaviour in UHCI and OHCI. TODO list: USB tablet should also return NAK (doesn't work yet), review xHCI for the NAK behaviour, accurate implementation of the idle duration
