For the past few months I have been having to unplug and reinsert my usb 3G stick, an huawei e172 to get it detected properly by vodafone mobile connect card driver for linux 2.0.beta3

I finally came across this comment on launchpad https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/105545/comments/46
Basically you just need to disable a certain unnecessary module called airprime
in the terminal type:-
sudo nano /etc/modprobe.d/blacklist
then add:-
# remove e220-conflicting airprime
blacklist airprime
that's it. So simple and yet so pleasing that the 3G stick just works first time now.
