Me too I am afraid. Using Lucid, with a BlueNext BN-WD54g USB adapter (lsusb gives ...Ralink Technology, Corp. RT2501USB Wireless Adapter) . Used to work fine on all previous version (from about 6.x).

Behaviour is most odd. Just spent an hour trying to get it to work - different USB ports etc, redoing connection settings, rebooting router, different but same model adapter. Then plugged in a 3COM adapter to same port which started working straight away. Just for fun, I then plugged in the bluenext device as well - and it started working, and continued to work after the 3COM was removed. I then unplugged it, then plugged in to a different port and it kept working, so plugging in the 3COM seems to have kicked the system in to working! Like I said - odd!
