socket.error: [Errno 107] Transport endpoint is not connected (Gentoo)

See original GitHub issue

I got this error when trying to run ps4drv on Gentoo. The entire trace is :

I just experienced the “Transport endpoint is not connected” error. I have 2 dongles. The first one works fine and it’s a bluetooth 4.0 usb dongle. The second one gives me the transport error and it’s a bluetooth 2.0 usb dongle.

The fact is that standard pairing is also problematic because it asks for a PIN, which does not happen to be necessary with the other device.

I managed to pair it using bluetoothctl after enabling the agent:

[bluetooth]# scan on
[bluetooth]# trust MAC
[bluetooth]# agent on
[bluetooth]# pair MAC
Request PIN code
[agent] Enter PIN code: 0000

And then “ds4drv --hidraw” worked fine.


  • Without the “agent on” command, pair fails with “Failed to pair: org.bluez.Error.AuthenticationRejected” with the bluetooth 2 dongle.
  • The agent/pin steps are not necessary with the bluetooth 4 dongle.

I’ve read a lot of docs && I suppose that it’s due to bluetooth dongle… It has bluetooth 2.1
