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. – Alex Cucu Aug 24 '12 at 11:56

    I had a same problem, because I was using a powered USB HUB, plugging it in normally solved my problems. Maybe try that :) – DanFritz Sep 20 '12 at 22:43

    Have you solved this? We're trying to clean up the site and this one has been dead for a while. – RPiAwesomeness Jan 11 '14 at 04:54
  • 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. – Goyuix Jan 11 '14 at 15:40
  • 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. – Matthias Urlichs Feb 05 '14 at 20:26
  • Goyuix - you might want to put that as an answer, though. – Bex Apr 20 '14 at 08:40
  • I had a similar issue a while ago and then I got a 5v 2A micro-usb power supply and haven't ever had an issue since. They're like $15.00on Amazon! I'm currently running a 2TB USB 3.0 external hard drive, HDMI, audio, ethernet, and of coarse the Raspberry Pi off of it. – Jared L. Aug 01 '14 at 17:11
  • I've put an inquiry in to Qualcomm about the power needs of the AR3011 chipset in different modes. We'll see if that yields any specific fruit. – zerolagtime Aug 12 '14 at 23:33

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.
