Well, what you can do is

 - Test if the proposed fix (or 2.6.31.5) works for you, if yes, then
just wait since I expect Canonical to release that update soon

 - If not, please send the usbmon logs I've requested about 3 times so
we can actually track down what the "other" problem might be :-)

As to how to do that usbmon logging, it's very easy:

 cat /sys/kernel/debug/usb/usbmon/0u >log_file.txt

And then plug the modem, wait about a minute for "things" to happen, and
ctrl-C the above command & send us the log file (along with the dmesg
output snapshot -after- the log has been taken).

Cheers,
Ben.
