I bought one of these, and so far, I've managed to get it to install and find my laptop and phone. To get it to work, I installed Bluez using
Then I created a hcid.conf file in /etc/bluetooth, based on Code Listing 3.3 on this page
(yes I know it's Gentoo, not Debian, but it's Linux, innit?).
Then I restarted the BT daemon with:
and the bluetooth device hci0 was up and running. hcitool scan found my phone and laptop. I'll investigate further when I have a decent internet connection for the pi. Bridging my laptop's wifi seems to be unreliable.
I did notice, however, that the dongle didn't like my USB hub. It didn't even like the ps2-USB adapter my keyboard and mouse are connected to running off the hub. I'll have to investigate that further, too. I'm gonna make a USB lead with no power wire to see if that makes a difference.
My ultimate goal for the BT, for now, is to be able to connect a PS3 remote to the pi for XBMC.
