Cheers to you.
I got a problem in making a Mobile-BroadBand connection in Ubuntu 11.04, using 'Huawei e303c' usb data-card. I'm using Tata Docomo 3G sim-card (India, circle: Maharastra).
My observations:
-
I installed the device's driver 'Mobile-Partner For Linux'(which came up with the device). But it is not detecting my device.
-
In Network Manager, Adding a Mobile-BroadBand connection is not able to detect the device (with or without the device's driver installed).
-
I tried softwares like usb_modeswitch, gnomeppp, wvdial, sakis3G and followed their guidelines. These too didn't work.
-
Without the driver, the system is able to identify the device (Mobile-Partner icon comes-up, that leads to driver setup files). But after installing the driver, nothing comes-up there.
-
In all the above cases, when 'lsusb' cmd is fired, the prompt shows the connected data card (as 'DEVICE_ID:VENDOR_ID Huawei Technologies Ltd.,').
This is my problem. Give a solution to get my device connected.

I encountered the same problem. Earlier the datacard was working fine with Ubuntu 12.04, without installing any software. But as soon as I installed the linux drivers which were bundled with the device, it stopped working.
After a lot of searching, and digging into the install script, I found a simple solution. Run the following commands in the terminal, to get Huawei E303c working again:
These commands will reinstall usb-modeswitch. Actually, the whole problem arises because Huawei drivers modify the usb-modeswitch data files, reinstalling them will solve the issue.
