It works fine at the Grub screen.

It *doesn't* work for the kernel when it initially starts up, even though a few
seconds ago the hardware worked just fine.

It *does* work after I've unplugged/replugged it - I've tested both the USB
side and the PS2 side, in either case it starts working.

I'm not sure what difference "plug it in after it's running" and "unplug/
replug" will have. I suppose I could test that, but I'm suspecting the results
will be "it works fine after plugging it in once the kernel is up".
