I specifically asked to run ?btmon -w ? before plugging in the device. I want to see the early setup process here. What would I do with a hcidump trace. Hi Marcel, The attachment is the logfile generated by "btmon -w ". And the logfile was generated by below steps, 1) boot up the system into the ubuntu desktop 2) open a terminal and run "sudo btmon -w ~/lenovo-m4400s-btmon.log" 3) open bluetooth applet and click adding a new device, the bluetooth begin to scan devices 4) power up the bt headset 5) laptop bt module find the headset and connect it successfully 6) open the sound applet, choose bt headset as output device, play sound, but no sound can be heard from bt headset 7) Ctrl+C to terminate the "btmon -w " In case you can't receive the attachment, i decode the logfile and paste the content here. Thanks, Hui. ================================================================================================= Bluetooth monitor ver 5.9 = New Index (BR/EDR,USB,hci0) [hci0] 0.218046 > HCI Event
