Can you please attach the output of the following command ?

$ sudo lsusb -vv

Same problem here with a Debian Sid / 2.6.34-1-amd64.

The adapter seems to be in HID mode[1] at boot time, ie wireless keyboard and mouse are working but in restricted mode (no multimedia keys, no fn key, etc..).

I tried to play with hid2hci tool with no luck:
 - changing the bluetooth adapter to hci mode has no effect.
 - changing the pseudo usb hub (0a5c:4500) to hci mode causes the bluetooth host (05ac:8215), keyboard (05ac:820a) and mouse (05ac:820b) to be disconnected but then launching `hcitool dev` reports no device.

Interesting part from lsusb:
Bus 001 Device 007: ID 05ac:820b Apple, Inc. Bluetooth HOST
Bus 001 Device 006: ID 05ac:820a Apple, Inc. Keyboard
Bus 001 Device 005: ID 05ac:8215 Apple, Inc. Mouse
Bus 001 Device 003: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

I think the problem is that bDeviceClass for 05ac:8215 is 255 (Vendor Specific) instead of 224 (Wireless).
Il solved this by adding the device to the generic bluetooth usb kernel driver.

Now it works but I had to remove keyboard and mouse from OS X before adding them in Debian => HID emulation do not work anymore at boot time...

Hi,

I'm pleased to announce that the patch has been accepted upstream:
http://git.kernel.org/?p=linux/kernel/git/holtmann/bluetooth-next-2.6.git;a=commit;h=acc359441e4e79b6eac758404d50e1f12d3866f1

[RussianNeuroMancer (russianneuromancer)]

This patch is a part of 2.6.35 kernel?
This issue is reproducible in Maverick Beta LiveCD?

[Cyril Lacoux (clacoux-ifeelgood)]

The patch is a part of the following upstream versions:
 * 2.6.32.19, see http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.32.19
 * 2.6.34.4, see http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.34.4
 * 2.6.35.2, see http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35.2

And will be a part of the upcoming 2.6.36 release.

Still issue in Natty?

[Cyril Lacoux (clacoux-ifeelgood)]

As I said, I don't use Ubuntu, but it should be fixed since kernel version for Natty is 2.6.38.
