Make sure that the device didn't get renamed to a new number/instance.
This happens a lot on USB devices, since they allow hot plugging.
The system might be seeing it as a new "second" device, and ignoring
the first one. This happens when you move a graphics card to a
new slot, too. It will now appear to be fb1 in the new slot, not fb0.
I've also seen this occasionally happen when new drivers are loaded.
It forgets all the old stuff, and creates new ones.

This may have happened to the kbd and mouse, too. But the system
knows about those, and will always search for one of each and
make it the default one.

You might need to do a "boot -r" to re-detect this, too.
"reboot -- -r" works from unix.
