Subject: [PATCH] hso: fix for the 'invalid frame length' messages
Date: Mon, 30 Mar 2009 11:44:59 +0200 [thread overview]
Message-ID: <20090330094459.GC9849@raptor> (raw)
From: Jan Dumon <j.dumon-x9gZzRpC1QbQT0dZR+AlfA@public.gmane.org>
Some devices cannot send very short usb transfers. To get around this the
firmware adds a known pattern and flags the driver that it should check for
this pattern on short transfers. This flag was not taken into account by
the driver.
