Starting from hibernation

I have an ASUS P5E3 Deluxe with the latest BIOS. Despite setting all
external startup types to 'disabled' in the BIOS, when it's hibernated
the system will restart if a peripheral such as a printer is switched
off or on. Is this normal? Incidentally, it will also restart
sometimes when the mouse is moved. Both printer and mouse are USB
devices.

When you go to Device Manager, and do Properties on some
devices, you'll see a tick box next to

"Allow this device to bring the computer out of standby"

Perhaps if you untick the box, then the device will stop being
a trigger event for wakeup. For example, my PS/2 keyboard and
my PS/2 mouse, have that box ticked right now. But my PS/2
keyboard is powered from +5V, and that power source if dead
when the computer is in standby or hibernating. Some other
interfaces, such as my USB ports, could be powered from +5VSB,
and that voltage is present during standby.

So disabling all USB responses, such as the computer waking
up if a peripheral gets plugged in, might be a bit tougher.
Especially if there isn't a specific item for it in the
APM configuration or Power Management types of BIOS pages.
I don't think USB ports are covered by "Power On by PCI Devices".

No, I don't think they are. I've just checked properties for a few
USB devices, including "printing services", and there's no box to tick
that stops the computer coming out of standby. OS is XP Pro SP3, btw.

It's not a problem as I have a switched power rail (two, in fact) for
computer and bits, and two other separate sockets for router and
modem, so I can switch everything off as I choose.

Just thought I'd ask. Thanks for the help.

Go into Device Manager. You should see "Universal Serial Bus
controllers" near, or at, the bottom. Click on the plus sign and all
the USB ports should be listed.

There should be a number of instances of "USB Root Hub". Double click
on each one and select the "Power Management" tab. There are two boxes
to be checked, or unchecked, one to "Allow this device to bring the
computer out of standby". Although on my system, the selection is
grayed out, you may be able to unckeck it on your system (if it's
checked, obviously).

I just looked at all of those root hub "allow to bring out of standby"
boxes and they're greyed out but all unchecked. So that bit of power
management doesn't appear to be working.
