Unfortunately that's not too helpful either. I suspect some other part
of the system is supposed to turn on the Bluetooth device but is
failing to do so.
Here's something else you can try, under 2.6.39. Do this (as root):
echo 0000:00:1a.0>/sys/bus/pci/drivers/uhci_hcd/unbind
dmesg -c>/dev/null
echo 0000:00:1a.0>/sys/bus/pci/drivers/uhci_hcd/bind
dmesg>dmesg.out
and then post the contents of dmesg.out.
Another thing that might help: Collect a usbmon trace for bus 0 while
doing the above experiment. Instructions are in
Documentation/usb/usbmon.txt; basically all you need to do is mount a
debugfs filesystem on /sys/kernel/debug and then do:
cat /sys/kernel/debug/usb/usbmon/0u>usbmon.out
in a separate window before running the commands above. When the other
commands are finished, kill the "cat" program and post the usbmon.out
file.

Hi Alan.
I'm attaching the outputs.
