The hciconfig cannot initialize my bluetooth antenna.

When I first insert my BT antenna into an USB slot on my machine, the dmesg command emits the following sentence four times:

'Bluetooth: hci0 command tx timeout'

any time I try to run one of the initializtion commands of hciconfig (e.g. hciconfig hci0 up | reset | etc.), the hciconfig says: 'Can't init device hci0: Connection timed out (110)'

Hi,

2013/8/28 atar <atar.yosef@gmail.com>:

When this message occurs, any error in dmesg is displayed?

Could you get log of hcidump?

$ sudo apt-get install bluez-hcidump
$ hcidump
$ sudo hciconfig hci0 reset (other terminal)

If you have an error similar to the URL if you need a patch to the kernel.

As for your request, here is the log of the 'hcidump' command either when
I execute the 'hciconfig hci0 up' or the 'hciconfig hci0 reset' commands:

In addition, when I've tried to execute the 'hcitool spinq BT-ADDRESS'
command, the system has been crashed. this means that the GUI was crashed,
a lot of error lines were displayed and the system has stopped responding.

Hope this info will help solve the problem.

Dear Maintainer,

maybe I have a similar problem.

   * What led up to the situation?
I switched on bluetooth mode both at my radio and my laptop.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I successfully connected both, changed audio output to the radio and also
succeeded with this (the sound from the radio speakers was perfect).

   * What was the outcome of this action?
But then after some time playback stops.

   * What outcome did you expect instead?
Playback to continue.


Maybe this helps:
