I have 2 usb huawei 3g modems, an e220 and a k3765 which I use with 2
Dell Mini 10v's - I have one running lucid and one running maverick.
When I try to connect to my provider (vodafone) on the lucid laptop
running linux-image-2.6.32-25-generic (lucid) it connects with no
problem. The identical setup on Maverick (running linux-
image-2.6.35-23-generic ) the modem crashes when attempting to
connect... here is the syslog output... there are repeated
