Change the info.plist in the D-Link drivers to include the vendor and product ID for the WUSB11. There are instructions on doing it for an older version of the driver to get the MA111 to work somewhere, just follow them with the different product/vendor ids.
Many thanks to the KisMAC developers! I've been building revisions from source for a while now and appreciate the work everyone does!
I just got a WUSB11 2.5 on eBay (for US $17) and it works very well with KisMAC, finding more networks than Airport Extreme passive on my 12" PowerBook. However, I can't join any of the open networks it finds, because I don't have a driver. Google tells me a few people may have gotten it working by hacking the DWL-122 driver. All of the networks around me are too far away to be picked up by Airport Extreme, so I'd like to find a way to join a network with the WUSB11. What do you guys do? Any ideas appreciated.
