[SOLVED] Support for Huawei E398 USB Modem

Hi am trying to use my ISP provided Huawei USB modem. Arch detects the usb modem well. I connect and run the lsusb command to see the following:

Bus 006 Device 002: ID 12d1:1505 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard

But when i run wvdialconf /etc/wvdial.conf, i get the following message (the FAQ link there gave me a WSOD):

[njathan@OuchLinuX etc]$ sudo wvdialconf /etc/wvdial.conf 
Password: 
Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Modem Port Scan<*1>: S0   S1   S2   S3   


Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

Please read the FAQ at http://alumnit.ca/wiki/?WvDial
[njathan@OuchLinuX etc]$ 

Though i know mine is not a 220, i tried following some seemingly harmless instructions from https://wiki.archlinux.org/index.php/Huawei_E220
That did not help either. Can someone help me configure the USB modem?

note: If it helps my Indian friends here in any way... i am trying to get the Tata Photon+ datacard working.

Have a look at the modemmanager and usb_modeswitch packages.

Thanks Strike0.
Installed modemmanager, but it doesn't seem to help. Any pointers?

I am successfully using a USB modem with wvdial and usb_modeswitch packages. Try installing usb_modeswitch...

What gets logged to dmesg when you plug in your modem?
When you insert the device, do you get a new node in /dev?  It man be called something like /dev/ttyUSB0. 
Lastly,  I know nothing of  wvdialconf, but it looks like it is only scanning /dev/ttyS0 though /dev/ttyS3.  You may need to explicitly tell it to use ttyUSB0

dmesg logs nothing. I did a 'watch tail /var/log/dmesg.log', inserted the modem, but the logs show as if nothing had happened.

When you insert the device, do you get a new node in /dev?  It man be called something like /dev/ttyUSB0.

a new device /dev/sr1 is created

Lastly,  I know nothing of  wvdialconf, but it looks like it is only scanning /dev/ttyS0 though /dev/ttyS3.  You may need to explicitly tell it to use ttyUSB0

It does seem to be looking for ttyUSB0 as well... but there is no such file created in /dev.

Great. Don't forget to put to [solved], if it keeps working after reboot ;-)
