Date: Mon, 11 May 2009 17:12:03 -0500 From: David Fries <david@...es.net> To: David Griffith <dgriffi@...csubak.edu> Cc: Andrew Morton <akpm@...ux-foundation.org>, linux-kernel@...r.kernel.org, linux-usb@...r.kernel.org, todd@...es.net Subject: bad endpoint address, MOTU FastLane 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?
