Comment 3 for bug 1001825

A related problem is that every time I try to pair a new trackpad (or re-pair an existing one, e.g. by removing it from the list of known devices) it takes quite a few iterations with the bluetooth wizard. Sometimes the device disappears mid-pairing, sometimes I am asked to enter some random string of numbers (maybe the trackpad identified as a keyboard?) and sometimes it just plain 'fails' the pairing process.

This happens to me on a standard PC (non-mac). I use a bluetooth dongle and dual-boot Ubuntu with Windows. Needless to say, there are no pairing problems, or any other trackpad-related problems, on the Windows side of things. Note that on Windows I use the official Apple driver.
