I have an Apple BT keyboard and a D-Link usb BT adaptor.
I have had it up and running in linux now for quite some time without
any trouble. I reboot, turn the pc off, whatever, the bluetooth always
works.
But today I booted my pc into windows (half life 2 lol) and thanks to
service pack 2 I can now use my BT adaptor in windows so I fiddled
around and got the apple keyboard connected.
So now I reboot back into linux and I cannot for the life of me get
bluetooth working again! I have had the pc/keyboard off for an extended
period of time, unplugged and plugged the adaptor back in, nothing will
get this keyboard connected again!

I used the same passkey in windows as I do in linux (0000). I honestly
cannot see how running BT while in windows would have any affect on its
functioning in linux, especially after everything has been off for a
long time in between.
The only reason I suspect there is a connection is that I had this crop
up in the past. For the longest time I stopped using the apple keyboard
because after I had it working in linux I rebooted into windows the same
day and then it never worked again in linux. I chalked it up to my
stupidty but here again it is happening.
Any idea what is going on here? Is this all unrelated? Thank you for any
insight.

the link key is invalid when you pair the two devices on a different
operating system. It is that simple, because a new link key deprecates
the old one.

actually it is not very easy to share the link key between two operating
system. The only way this may work is when you store the link key on the
Bluetooth chip directly. However nobody has written support for that so
far.

Marcel,
What is that problem with the link_key file. I have to remove that file from
time to time too. I use a usb dongle and have to connect my device sometimes
to this system sometimes to another.
Could you explain why a link_key file could get 'out of sync' ?

Ah wonderful! It took a few tries but it is happy again!
Now in the future if I find myself back in windows will I be able to use
it there without fear of disabling it in linux or should I just not use
it in windows any more?
Thanks again,
Patrick

the problem is the same. Error 0x05 means "Authentication failure" and
this means that the link key is wrong. Since we don't have an easy way
to delete a single paired device from our list, you need to remove the
file /etc/bluetooth/link_key and restart the hcid. After that, your
keyboard should re-pair again.

If only they would release I linux version of half life 2 this problem
wouldn't exist!

For some reason I was under the impression that auth and encrypt had to
be on for the Apple Keyboard.
I have turned them off and restarted but I am still receiving the same
error. Do I have to do something to reset the device? I took the
batteries out.
Thank you,

Hi Patrick,

no you are not. But as I expected you activated auth and encrypt and so
your device is in security mode 3 which causes a problem. As I said many
times now, do this only when you know what you are doing.

you re-paired your keyboard with Windows and thus the Linux side
provides a wrong link key now. What does "hciconfig -a" say?
