Subject: [PATCH 01/02] USB: sierra: Add TRU-Install (c) Support [ATTEMPT 4]
From: Kevin Lloyd <linux@...rrawireless.com>
This patch adds compatibility with Sierra Wireless' new TRU-Install feature. Future devices that use this feature will not work unless this patch has been applied.
This attempt of the patch corrects a hard-coded return and the dev_dbg messages form the previous patch submission.
This patch was tested on the 2.6.21.1 kernel source patched with the following patches (found at http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/patches/usb/):
usb-sierra-cleanup-urb-startup.patch
usb-sierra-fix-status-usage.patch
usb-sierra-status.patch
There were three previous submissions for similar support (6/6/2007 & 6/5/2007 & 7/11/2007) they were however rejected so please disregard those.
