bad endpoint address, MOTU FastLane

[David Fries <david@fries.net>]

This is a USB Midi device.  The device used to work, David Griffith
from a previous e-mail lists 2.6.17 works 2.6.18 doesn't.  The USB
midi driver talks to it using interrupt transfers, it doesn't need the
Isoc transfers.  usb_submit_urb returns -22 EINVAL invalid argument as
it is trying to submit an interrupt packet to what is registered as an
isoc endpoint.  The second interface has the same end point addresses
as the first.  Any suggestions on how to deal with this class of
broken hardware?
