Can you tell the exact location? It certainly makes sense, just
I didn't see it explicitely in the spec.

Also Linux/FreeBSD/whatever. Remains the question why noone
else has this problem appearently. Perhaps just a single
wrong device... Google found a file where USB IDs are collected:
http://siv.mysite.orange.co.uk/downloads/usbdevs.txt
There are 3 Belkin Bluetooth device IDs (0081/0083/0084),
and there is no sign of an ambiguity about device ID 0121.
