[Bug 268502] Re: Bluetooth doesn't work (hci_cmd_task: hci0 command tx timeout)

[Mark F]

I just tried the bluez 4.32 downgrade workaround on Ubuntu 10.10 and the
basics work ok with Blueman but I hit a serious issue:

Dec 21 21:14:21 linux bluetoothd[1375]: link_key_request (sba=00:22:43:D3:50:4D, dba=00:23:7F:81:DC:01)

Dec 21 21:14:22 linux pulseaudio[1919]: module-bluetooth-device.c: 00:23:7F:81:DC:01 is not known.
Dec 21 21:14:22 linux pulseaudio[1919]: module.c: Failed to load  module "module-bluetooth-device" (argument: "address=00:23:7F:81:DC:01 profile=hsp sink_properties=device.icon_name=blueman card_properties=device.icon_name=blueman"): initialization failed.
Dec 21 21:14:22 linux bluetoothd[1375]: Badly formated or unrecognized command: AT+PLTWB=4
Dec 21 21:14:22 linux bluetoothd[1375]: Badly formated or unrecognized command: AT+PLTWN=1

Blueman's PulseAudio.py reports failure to load "module-bluetooth-
device" (python call to C lib string).  So no audio is possible but
device is discovered ok.

I'm using Plantronics Voyager Pro perhaps that is contributing to this
workaround not being successful but FYI.  I'm going to attempt
installing the latest build of bluez next.
