[Bug 554099] Re: [PATCH] Qualcomm Gobi 2000 3G (gobi_loader/qcserial) broken in 10.04

[lapistano]

@Simon: turned out I needed to reload the qcserial module and 'killall modem-manager' to get the modem recognized  by the network manager. Once it is listed as an interface in the network manager I can connect to the network using it. As I am now.
I attached the syslog of establishing the connection. I can see the 'unknown error 100' lines as you experiencened in you log, but I do have a stable link with no hickups.

hope this helps
