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.
