FYI the registry patch works on desktop PC's also, mine being the Athlon XP Barton running DFI Lanparty KT400A motherboard.

With the patch CPUidle extreme software shows drop in CPU core temperature back to normal with USB plugged in. Before, the CPU would run around 12% CPU cycles with the USB plugged in no matter what.
