Glad to see you're still paying attention to these USB cellphone issues,
Leann.  I've searched far and wide for a solution to this problem and
have found nothing so far.

I have an unlocked GSM LG MG810.  (http://www.phonearena.com/htmls/LG-
MG810-phone-p_1529.html)  Using Windows, it mounts as a USB mass-storage
device.  Running Kubuntu 9.04 with 2.6.28-11-generic, I get this
sequence in /var/log/messages:

cannot read device status, Broken pipe (32)           

So the kernel has no trouble detecting the device, but it fails to
mount.  I've tried this with four different computers of various
vintages, all running Kubuntu 9.0.4, with no success. I'll give karmic a
try when I get a chance.
