I've read several other threads about that Jawbone, and people haven't had any luck connecting to Windows 7 or OSX. I know that the new software works, because I tried pairing my original Jawbone to Windows 7 and it didn't work, but I was automatically alerted that new Broadcom software was available. I downloaded it, the application found my hp bluetooth adpater and installed the updated drivers
and software, and then I could find, pair, and use my original Jawbone as a headset. In fact, I'm listening to iTunes over my Jawbone right now!
Based on the Broadcom application, and the picture referenced in the link I posted, I think the Broadcom software can't find your adapter. Was it plugged into your computer before you ran the update application? Can you borrow a friend's bluetooth adapter and try using that one?
