In trying out my USB scanner I contacted the guy responsible for the
usb scanner code. Included is the discussion. I was wondering whether
anyone knew how to tackle the problem he states. - i.e can the second
IN endpoint be ignored?

Hi Bryn,
Thanks for including the messages file. The problems lies the fact that
scanner.c only operate in two modes: (1) two bulk endpoints (for for IN
and one for OUT) or (2) the same as (1) but with an interrupt endpoint.
The Primax has three bulk endpoints (two IN's and one OUT). I don't know
if the additional IN endpoint is important or not much less why it is
there. If it can be determined that the extra IN is not required then the
code could be written to silently ignore it. Since I don't work at the
scanner level (only the driver level), others must investigate the actual
scanner peculiarities.
Regards,
/\/elson
