hello folks...

yesterday, i upgraded to the new bluetooth firmware 1.1 from apple.
afterwards, bluetooth still worked on OS X, but not in linux anymore.
the months before, bluetooth worked just fine with hci-usb, thank you.
now, hci_usb is not even loaded automatically and when it is loaded
manually, there is no device hci0.
by chance, i found out, that the values in /proc/bus/usb/devices show
other values now:

T:  Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2

look at the device in lev 01 which used to be the bluetooth device.
interestingly, the release notes of the firmware talk about improvements
when handling mice and keyboards (see class + proto above).
this is the output of the old /proc/bus/usb/devices:

very strange, indeed.
i attached the info i could gather from OS X and the relevant output of
"lsusb -vv" for both firmwares.

my question now is, if there is any hope to fix this. i worked a little
on hci_usb.c. first, i added the device id statically to bluetooth_ids,
then i tried to hardcode the endpoint data into husb->*_ep which i could
not complete yet due to some missing data. but will this be enuff? is
there more to do? do you need more info?

luckily, i found a way to use the old firmware, simply overwriting the
new one does not work for some reason. you have to force the firmware
updater to load the old firmware in OS X, then warm-boot into linux. the
next time you boot into linux, the new firmware superposes the old one again
and you have to load the old firmware under OS X again. weird and it
does not always work.

thanks in advance,
 sebastian
