For months now my mobile broadband (GSM) stick has worked with Crunchbang. Yesterday it stopped. When I plug it in, it appears in the network manager and I can connect to it, but as soon as it is connected it disconnects.

I switched to Liquorix kernel about 1.5 weeks ago and the stick worked with it as well, until now. Switching back to the original kernel does not fix it.

Computer: Lenovo U410

GSM stick: Sierra Wireless USB 308

Has anyone run into this before and knows how to fix it?

EDIT: Added dmesg output

EDIT: Trying to set usb_modeswitch

sudo usb_modeswitch -v 119 -p 68a3 -S

Output from that:

Looking for default devices ...
    No devices in default mode found. Nothing to do. Bye.

EDIT: Fixed typo in the usb_modeswitch command

sudo usb_modeswitch -v 1199 -p 68a3 -S

The command ran properly that time but to no effect.

SOLUTION:

After testing the device on multiple computers and multiple OS's it would seem that there are hardware problems. I can't add this as an answer yet.
