And their baseband was based on Silicon Wave which actually got bought by Qualcomm if I remember this correctly. So going by the manufacturer id and adding a good comment into the code might make this work nicely again. Johan, if you prefer a quirk, then go for that one. > Should I open my trash bin? It is nice to have these old-timers around. And we do want to make them work. Knowing where they fail is actually pretty good. Then again, it is a Bluetooth 1.2 dongle and your are missing features like Secure Simple Pairing or Low Energy.
