[Bug 554099] Re: qualcomm gobi (2000) mobile broadband module not working after upgrade to lucid

[Brian]

I got this to work on my Dell E6410 with the "Dell Wireless 5620" Gobi
2000 over Verizon Wireless.

I found a pretty good walk-through I could adapt to Dell/Verizon at:
http://www.nulldevice.de/2010/06/wwan-lenovo-thinkpad-x100e-ubuntu-10-04/

I updated to the 2.6.35rc1 kernel, and built gobi_loader. The Dell device is in qcserial based on extrapolation from:
http://cateee.net/lkddb/web-lkddb/USB_SERIAL_QUALCOMM.html
(Dell device is: ID 413c:8186, or 413c:8185 before firmware is loaded.)

I got gobi_loader working with what I thought were the Verizon firmware
files, but after the card was activated with Verizon it still would not
connect.

Finally I imaged my primary partition to my /home partition and wiped
it, installed Windows 7 64b and the Dell drivers, then "activated" the
card. It then connected in Windows fine. (I think the process of
"activating" the card in Windows is just choosing the correct firmware
to load.) From my Windows 7 install, I copied the firmware files to a
USB stick and restored my Ubuntu installation. A warm reboot resulted in
the card working from Ubuntu. However, a cold reboot and the card
stopped working, and the Gobi 2000 acted like it did before running
Windows. I pulled the firmware files off of the memory stick and looked
at the md5sum values for the files. The firmware I got from the Dell
install was different from the Lenovo firmware. So I copied the Dell
firmware for Verizon (from the 1/ directory) to /lib/firmware/gobi/ and
did a cold reboot. Now the Gobi 2000 is working!

Here are the md5sum values for the "Dell Wireless 5620" firmware:

$ find -name "*.mbn" -exec md5sum {} \; | sort -k 2

The directory structure seems to be the same--Verizon firmware is in the
./1/ directory. Although the firmware that is available is different.
