Off topic: do your USB ports power off when the system shuts down?
Mine don't -- the +5V continues on them.. I'd love a tip on how to
turn them off completely at shutdown.

Most Asus boards have jumpers for the USB ports to select between +5V
and +5VSB (stand by power). The reason to provide standby power is so
that keyboards with power buttons can remain powered so that you can
turn the system on using the usb keyboard. If you want to power off the
ports entirely, jumper them to the +5V line instead which only has power
when the system is on.

That's nice.

But the P5B-VM board does not have any such jumper for USB,
nor does it have any obvious combination of BIOS-setup options
to accomplish it.
