Bluetooth Adapter not recognized (precise)

[tim]

My specific dongle has worked flawlessly on 11.04, since upgrading, my system no longer recognizes it.

blueman-applet reports no adapters found.

hcitool dev reports nothing, just "Devices:"

lsusb finds this however:
Bus 006 Device 002: ID 1131:1004 Integrated System Solution Corp. Bluetooth Device

If I pull the dongle out, the applet disapears. If the dongle is not evident on boot, the applet will not start.

hciconfig show this:

Tailing syslog while attempting to `hciconfig hci0 up`shows this:

Status changed to 'Confirmed' because the bug affects multiple users.

Can't read version info hci0: Connection timed out (110)

However. two weeks ago it found devices, then the wholy system froze. Now, it searches an never finds devices...
Audio Out via HDMI is also not working on my now "ancient" amd-780G-based phenom quad... Sad, oneiric did not have these problems, instead it refused to shut the computer down...

I have a dongle that seems to be affected as well. I tried booting to a live cd of Natty and found that it still works fine there. I also tried booting a live cd of oneiric and found that it doesn't work there. Of course it still doesn't work with precise.

It is still not fixed on most undated ubuntu os as on Mar 6, 2014 and that is ubuntu 13.10. Any workarounds?

[Konrad Zapałowicz (kzapalowicz)]

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
