Subject: [PATCH 01/02] Sierra Wireless - Add TRU-Install (c) Support
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 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 two previous submissions for similar support (6/6/2007 & 6/5/2007) they were however rejected so please disregard those.
