It works only if the device on the port (cordless mouse, in my case) is
unplugged before sleep. With the device plugged in, it briefly powers up
then powers down again on wakeup. No idea if the device being in use
prevents your code from taking effect.

Pre-2005 PB G4 17" 1.5 GHz in case it matters.
