Hello all,
I've found that the Belkin_sa drivers in the 2.4.5 kernel do
seem to support the Belkin F5U120-PC (4 Port Hub, 2 PS/2, 1 LP, 1 Serial)
Serial port. It only seems to require adding the appropriate entries
for the additional product code (050d:1203), tables, and initialization
to belkin_sa.[ch].
This almost seemed TOO easy but I haven't run into a gotcha yet.
It's talking to a modem successfully and I'm about to try out an IrDA
dongle (an old Belkin serial IrDA module, no less).
All the other functions on this hub (LP and PS/2 as well as hub)
are already supported.
The diff is small. Attached below.
Mike
