Hello list,
I'm trying to pair Bluetooth USB dongle and Bluetooth headset
and facing a trouble.
Detail of devices are described below.
The problems happens on kernel 2.6.39,
while on kernel 2.6.26 it works fine.
I know that after 2.6.26 bluetooth driver in kernel source tree changed,
especially hci_usb changed to btusb.
To let my USB dongle work on 2.6.39, what should I do?
I'll dig into source code if it is necessary, but I don't know
where is the good place to start.
Does anybody have idea? Suggestions, hints are also welcome.
I already enabled dynamic debug facility in kernel, and
set +p to some files.
echo -n 'file hci_core.c +p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'file hci_event.c +p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'file hci_conn.c +p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'file l2cap.c +p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'file hci_sock.c +p' > /sys/kernel/debug/dynamic_debug/control
echo -n 'file af_bluetooth.c +p' > /sys/kernel/debug/dynamic_debug/control
Followings are information related to the USB dongle.
