Hi Marcel,
Matthew here again.
BT keyboard is connected on startup, but no keyboard output is
happening, and capslock light does not turn on when capslock key is
pressed. This is not just the connection delay, as my mouse reconnects
successfully after boot.
This is on kernel 2.6.9 with the mh3 patch, bluez-libs and bluez-utils
2.11. I have debug output enabled in the hidp module, and bluez-utils
and bluez-libs are compiled with debugging enabled. Debug output
follows.
As you can see a BT connection exists to the keyboard, key events are
actually coming in, but they are not getting through the kernel hid
layer. I press the <return> key, and no output appears in a terminal
that has focus. From the below, do you have any idea where I should
start looking and what to check? Any debug in the kernel hid_core.c
that I could turn on? Critical events and functions in the kernel I
could printk()?
I believe the Apple Open firmware on the powerbook negotiates a
connection with the keyboard on power up or boot, and leaves the
built-in CSR USB dongle in USB HID emulation mode. The keyboard starts
working after I switch it on and off, and it renegotiates a connection.
Here is some hidd/hcitool output:

Thank you for all your help. Its going to be good to get this sorted,
as I have to deal with this issue every time I switch my laptop on, and
switching the keyboard on and off will wear its switch out.
Next I will write some code to properly enable the keys on the Apple
keyboard (F13, F14, F15, F16, Clear, help, numeric =, sound keys, eject
key)
Cheers,
Matthew Grant

No, there are definitely key press events coming through the BT stack.
The debug I sent shows it, and it has been confirmed with more than just
a cursory observation. They are NOT getting into the HID layer. That
is what I want to look at it, after checking correctness of incoming
events and negotiation.

That is applied, to this keyboard, and the other one that does not
behave like this.

Yes, I do not want to broadcast passwords for everyone to listen to.
Also, I have a second keyboard that does not behave like this...
We won't really know what is going on until things have been examined.
I was after some pointers on where to start looking at the hidp.ko
interface and the connection negotiation with the kernel HID core. This
is obviously the first place to look and check from what has been
observed so far.

Thanks for that bit of info.

maybe the keyboard firmware is buggy. I read that Apple has a firmware
update for their mouse and keyboard and I think it is worth to try it.
Do you run your Bluetooth device in security mode 3?

It is all on the CSR BlueCore02 chip. The Apple firmware does nothing.
