I know you now have a fix, but I didn't see in this thread if you tried
a full hard power reboot.  The old PS/2 connectors where never designed
to be hot pluggable (depending on motherboard implementation). On some
newer mobos, the PS/2 DIN is actually converted to USB internally - and
is thus hot pluggable. The USB-PS/2 DIN adaptors can muddy up this as
well. I've found also that the PS/2 DIN combo versions (for keyboard OR
mouse) often need a full power cycle.

All this is due to the OS (any species) getting the hardware info from
the BIOS instead of a clean pass through. If the BIOS don't see it,
neither will the OS.

In the BIOS there is also sometimes a setting for "plug and play OS". If
that is ON or YES, then the BIOS does no hardware detection and just
passes everything to the OS to detect.  I recommend turning this on for
any Linux OS.
