A friend has a MacBook. If it's sent to sleep, it will wake up again

Any idea what might be causing this?

It sounds to me like some sort of hardware issue.

I've had him send me the output from system.log. It includes:

IOUSBWorkLoop::closeGate - interrupt Thread being held offUSB caused
wake event (EHCI)

He also has some problems with USB - sometimes, devices attached don't
show up until after a restart.

Oh - and what's the Intel equivalent of an Open Firmware reset?
