Using the instructions in this answer I was able to get Bluetooth working with a small Asus branded USB receiver. I was able to see other Bluetooth devices in the area, but whenever I put my Motorola S10 headset in discoverable mode and ran the hcitool scan command, it would freeze up for a moment and then return with the error Inquiry failed: Connection timed out

I am guessing it is probably just missing the required bits to enable the A2DP and/or Headset profiles that the S10 is reporting back as supporting. Is there a package I can just apt-get and enjoy? For what it is worth, I installed bluetooth, bluez-utils and blueman through apt-get.

    You should try connecting the USB Bluetoorh dongle through a powered USB HUB. It might be a power issue.

    I had a same problem, because I was using a powered USB HUB, plugging it in normally solved my problems. Maybe try that :)

    Have you solved this? We're trying to clean up the site and this one has been dead for a while. Commented Jan 11, 2014 at 4:54
  • I haven't tried a powered hub (don't have one) but I did use a higher output (1A) 5V adapter and it seems to work. I wouldn't say the question is answered but available current does seem to be at to root of the issue.

  • Yeah, "get a stable high-current power supply instead of any old charger adapter you have lying around" seems to be the #1 solution to a lot of RasPi problems. Commented Feb 5, 2014 at 20:26

Although not officially considered "answered" by the OP, he did find a temporary solution, which I believe merits at least a stand-in answer until he finds a full solution. You can read the comment that I believe merits this stand-in here.

This answer can be removed as soon as the OP decides that he has completely solved the issue.
