You can tell the kernel to ignore particular devices that might wake the
machine up by:
sudo sh -c 'echo NAME > /proc/acpi/wakeup'
That will just toggle device NAME between enabled (can wake up) or
disabled (can't wake up). But the hard part is figuring out which device
name from /proc/acpi/wakeup is relevant to the USB keyboard. Maybe 'XHC'
representing the USB controller?
Your BIOS might also have settings to control which devices can wake the
machine up.
