The appearance certainly sounds like the Laser UDC I had,
but the behavior is totally foreign.  I must have booted
ProDOS on it forever before finally retiring my 5.25 media.
I never really used DOS 3.3 stuff much.

Have you tried switching the port the disk drive is connected
to?  Also, I remember the card is only fully functional if
you put it into slot 5.  If you do that, it automatically puts
3.5 drives into slot 5 and maps 5.25 drives to slot 6 when
everything is daisychained off of port 1 on the card.
