I'd say almost every USB Bluetooth dongle will work with bluez; but you might have to download firmware to get some working. Any Bluetooth dongle with a CSR (Cambridge Silicon Research) chip will work out of the box. I think most cheap dongles use this chip. I bought one from China for $5 with a CSR chip which worked fine until it fell apart. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
