Bug Description

SRU Justification


Non functioning Fn keys without hid-apple support.


Add missing device id for Apple wireless aluminum keyboard (model 2011)


Attach keyboard and use Fn keys.


Ubuntu 2.6.38-13.55-generic

The Fn key of my brand new Apple wireless keyboard (A1314) is not managed.

It seems because the hid-apple module is not loaded :

 input: Apple Wireless Keyboard as /devices/pci0000:00/0000:00:1a.7/usb1/1-3/1-3.6/1-3.6:1.0/bluetooth/hci0/hci0:42/input6
 generic-bluetooth 0005:05AC:0256.0003: input,hidraw0: BLUETOOTH HID v0.50 Keyboard [Apple Wireless Keyboard] on 00:1B:DC:00:F5:A9

Checking in kernel source product id 0x0256 is not known

I've added it and recompiled hid.ko and hid-apple.ko and now it works fine:

 input: Apple Wireless Keyboard as /devices/pci0000:00/0000:00:1a.7/usb1/1-3/1-3.6/1-3.6:1.0/bluetooth/hci0/hci0:42/input4

It looks like your device has been added to the upstream kernel and is also available in precise:

hid-ids.h:#define USB_DEVICE_ID_APPLE_ALU_WIRELESS_2011_ISO 0x0256

Did you open this bug to see if this can be backported to prior stable releases?

I just want to use my keyboard with Ubuntu 11.04 without having to recompile the kernel each time the kernel is updated.

This bug is awaiting verification that the kernel for Natty in -proposed solves the problem (2.6.38-13.57). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
