I tested a hub that reported 9 or 10 ports.
And I made changes to data structures to support that,
up to 16 ports anyway.  That part used to work after
my changes, but not before them, for a hub with more than
8 ports.

5 open USB ports, 1 PS/2 keyboard, 1 PS/2 mouse,
1 serial, 1 parallel port.  Total 9 ports, all seen
as USB.

Oh, email archives...
There are threads on this from 2000.
Patch was sent to Alan (for 2.2.19) on 2001-feb-20.  See:

Ah, I'm recalling it now:  Mobility EasiDock.

Yep.
