Can someone help me install my o2 data card.

lsusb gives me

Bus 005 Device 003: ID 1199:6880 Sierra Wireless, Inc.
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

I've done some digging and found it's one of the cards that acts as a storage device at first to install windows drivers. So I assume I need to use something like usb_modeswitch but I don't know how to use this and the documentation isn't up to much.

I've installed and configure Network Manager 0.7 and this works for wireless etc but doesn't recognize the data card.

Please help.
