Sierra Aircard Support,

Hi,

I am trying Sierra Aircard USB308/USB10U dongle. USB id is 0f3d:683a

Under usb_modeswitch.d I could not find the config file for the same but in http://www.draisberghof.de/usb_modeswitch/ written that Sierra Aircard modems are supported.

Can any one mention the configuration for these modems???

Please post the output of "lsusb -v -d 0f3d:68a3".

Hmm, I assumed there was a little twist in your product ID. Maybe "683a" was right after all. So you might want to try again with "lsusb -v -d 0f3d:683a".

Of course the device must be plugged.

Hi Josh,

The product id has been provided by the vendor as 68a3 only. but after I plug in the device, lsusb is not showing IDs properly.
It is showing, ids as 0000:0000.

I somehow started feeling, my kernel might have the support for this dongle.
Do you think, adding support for this id in kernel modules will help me to detect?

After pluging in, you may have to wait for a moment. Some 3G sticks need a while until they are appearing on the system. Run "lsusb" (without any parameters) to list all present USB IDs.

If you still don't see your device in the list, then there is a problem with the stick. Either it is faulty or it requests too much power from the host. This may be a problem with some netbooks or embedded systems which cannot provide the specified maximum power of 500 mA; 3G sticks usually announce that they want to have the full amount.

The kernel is not involved at this level except with the basic USB host support. If you had problems in that respect, then any USB device would refuse to work on your system.

If you see the USB ID of your device in the list after a while, run the first command I suggested again.

Mind that you may need to be "root" or use sudo with all these commands.

Hi Josh,

Thanks for your all concern. The problem got solved after I put sierra.ko within the system.
