Hello,
I want to test an headset on Linux with Bluetooth.
I use the adapter Ovislink EVO-BT2-100 (Bluetooth 2.0), headset
Motorola H270 (Bluetooth 2.1), Gentoo on Linux kernel 2.6.27.6 (with
the driver hci_usb, btusb doesn't pairing) and Bluez 4.26.
I have a problem similar to this discussion:
http://thread.gmane.org/gmane.linux.bluez.kernel/456
When I start the headset, the pairing process is ok, and the heandset
go into sleep/unpairing.

Next when I run the command "arecord -D bluetooth -f S16_LE test.wav"
Bluetoothd connect to the headset and start the record. But after 40s
the record stop (no file created) and bluetoothd make a connect timed
out :

With Strace I see it's a PF_BLUETOOTH (with ther kernel ??) socket error.
Recent Bluez 3.x make the same problem and old crash rfcomm in the kernel.
It's only work on Ubuntu Hardy, kernel 2.6.24 bluez 3.26 with "lm
accept,master;" and "lp hold,sniff,park;" (not in bluez 4),, but
2.6.24 is a bit old for ext4...
Thanks in advance.
Regards.
