I have a dodo USB modem in which I had used perfectly fine in 11.10. When I first installed Ubuntu I plugged the USB modem in and it worked perfectly as is.
However, since the new update it will not do such, I've tried updating all the software and what not, updated
ndiswrapper (although, it was worth a shot) and yet nothing works still.
I have also used lsusb as per on the MobileWirelessBroadband page and it is apparently there.

Not sure if I'm missing anything, so just thought I'd ask. ;-)
