I have an E220 and an E173 dongle.
The E173 initialises and connects fine the E220 does not.
I switch the same SIM between dongles.
Both dongles work fine on a friend's XP PC in the same location (again with the same SIM so I reckon SIM and dongles are all fine.
I have the same problem on another MINT 13 laptop.
lsusb output:
and here's a snip from syslog.log with the E220:Bus 002 Device 010: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E230/E270/E870 HSDPA/HSUPA Modem
I've googled and searched this forum, spent ages but haven't found any information except that E220 should work.Dec 10 16:20:14 rivendell NetworkManager[787]: <info> Activation (ttyUSB0) Stage 1 of 5 (Device Prepare) scheduled...

Has anybody any hints or steers - I'm pretty 'nix familiar but not that familiar with USB mobile broadband dongles.
