I have an Irvine (which may actually be Huawei) 3g USB modem. I live in India. I use ubuntu 12.04. I am using an airtel SIM card in the modem.
On plugging in the modem, it shows up in 'Edit Connections'. However, there is no option to connect to it in the list of available networks displayed on clicking the network icon (the one in the shape of a sector of a circle).
I have usb-modeswitch and usb-modeswitch-data already installed.
Here's the extra line in the output of lsusb when the modem is present :
Bus 002 Device 005: ID 20a6:f00e
I have also attempted the instructions on this page - 3G USB Modem Not Working in 12.04; and it's still not working! I've tried the modprobe, the echo to usbserial, and wvdial (which didn't detect any modem).
Could anyone please give me ideas on what I could try next ?
Here's the relevant lines from usb-devices -
T: Bus=02 Lev=01 Prnt=01 Port=03 Cnt=01 Dev#= 6 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=20a6 ProdID=f00e Rev=00.00
S: Product=Modem Device
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
As you can see, it's detecting it as a modem, but perhaps using the usb-storage driver.
