[PATCH 2.6.20-rc3 01/01] usb: Sierra Wireless auto set D0

[Kevin Lloyd <klloyd@sierrawireless.com>]

from: Kevin Lloyd <linux@sierrawireless.com>

This patch ensures that the device is turned on when inserted into the 
system (which mostly affects the EM5725 and MC5720. It also adds more 
VID/PIDs and matches the N_OUT_URB with the airprime driver.

  Whom based his on the Keyspan driver by Hugh Blemings <hugh@blemings.org>

  History:
+v.1.0.6:
+ klloyd
+ Added more devices and added Vendor Specific USB message to make sure
+ that devices are in D0 state when they start. This is very important for
+ MC5720 and EM5625 modules that go between Windows and Non-Windows 
+ machines.
+v.1.0.5:
+ Greg KH
+ This saves over 30 lines and fixes a warning from sparse and allows
+ debugging to work dynamically like all other usb-serial drivers.
+ klloyd
+ Changed versioning to v.x.y.z
+v.1.04:
+ klloyd
+ Adds significant throughput increase to the Sierra driver (uses multiple
+ urgs for download link). This patch also updates the current sierra.c 
+ driver so that it supports both 3-port Sierra devices and 1-port legacy
+ devices and removes Sierra's references in other related files (Kconfig
+ and airprime.c).
+v.1.03
+ klloyd
+ Adds DTR line control support and impliments urb control.
