** Description changed:
+ SRU justification (for LBM in Lucid):
+
+ Impact: Certain models of 3G hardware (Gobi) which apparently are quite
+ common, require several changes to work. First, the kernel module needs
+ to be updated, which requires larger modifications. Second, a new firm-
+ ware loader is required together with a matching udev rule.
+
+ Fix: In order to prevent regressions, the driver backport was done in
+ LBM and also adds a new binary subpackage (lbm-wwan). This package also
+ contains the loader and the udev rule.
+ NOTE! The drivers also requires firmware files which need to be manually
+ gathered as they are not redistributable.
+
+ Testcase: Without this backport no 3G connections are possible. Sevral
+ users in the bug report had successfully used the driver from the test
+ package after collecting the required firmware files.

03f0:201d Hewlett-Packard <-- HP un2400 Mobile Broadband Module (QDL
interface)
HP un2400 mobile broadband modem stopped working after i upgraded to lucid.
I can not load firmware anymore to my modem's Qualcomm Gobi USB chip using
gobi_loader.
http://www.codon.org.uk/~mjg59/gobi_loader/
There was no problems on previous Ubuntu version (Karmic, kernel
2.6.31*). As i understand all devices based on this chip will not work
on lucid, if this will not be fixed.
HP un2400 is recognized by kernel's qcserial module. qcserial.c was not
changed from 2.6.31 to 2.6.32.
After searching internet i found that this is related to changes in the
kernel's usbserial module:
"The qcserial driver is currently broken in 2.6.32 and later. It's due to the
switch to using kfifo for usb serial, but we haven't been able to work out the
actual cause. I'm looking at alternative approaches."
