[Bug 446146] Re: Several Huawei USB dongle don't work with kernel 2.6.31-12.40 (2.6.31.1 update related)

[Michael Rüttgers]

@mahela00: 
The Bug reported here should be fixed since kernel-2.6.31-15.49, as noticed in the ubuntu changelog:
-------------------------------------------------
linux (2.6.31-15.49) karmic-proposed; urgency=low
  [ Benjamin Herrenschmidt ]
  * [Upstream] (drop after 2.6.31) usb-storage: Workaround devices with
    bogus sense size
    - LP: #446146
-------------------------------------------------

So you could try to upgrade your kernel to 2.6.31-16.

The issues left seem to be related to the flip-flop behaviour of the Huawai modems.
For me the only thing that worked was using usb_modeswitch called by udev in-time.
Neither calling usb_modeswitch manually after plugging the stick in nor the use of modem-modeswitch did work for me.

In your case I would first try to upgrade your kernel and then I would
give usb_modeswitch a try.
