3G USB Modem Not Working in 12.04
- by Seyed Mohammad
When I connect my 3G USB Modem to my laptop with 12.04, nothing shows up in Network-Manager. This modem is working in 11.10 and the modem is shown in Network-Manager but not in 12.04 !!
Here are the outputs of lsusb and usb-devices on two machines , one with 11.10 and the other with 12.04 :
Ubuntu-11.10 :
$ lsusb
Bus 002 Device 009: ID 1c9e:6061
$ usb-devices

Ubuntu-12.04 :
$ lsusb

$ usb-devices

S: SerialNumber=000000000002

I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=(none)
As the output of the above commands show, the device is detected as a modem in 11.10 but in 12.04 it is detected as a USB storage (the device is both a 3G Modem and a SD-card USB adapter).
Any help ?!
