Hi!

"Jamesdonkey" is the manufacturer and "A3R" is the model. I think adding
manufacturer to non-apple list is suggested, just like commit
c4444d8749f696384947192b602718fa310c1caf,
20afcc462579c0bd79a59ab2b87b82ffa833d118, and
a0a05054583fed17f522172e101594f1ff265463 did.

However, my keyboard's hardware is buggy, in wireless and wired mode, the
manufacturer is empty, only model name exists. For your reference, the
result of `lsusb -v` is pasted below.

In wired mode, `lsusb -v` shows:

Bus 003 Device 002: ID 05ac:024f Apple, Inc. Aluminium Keyboard (ANSI)
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            0
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0        64
  idVendor           0x05ac Apple, Inc.
  idProduct          0x024f Aluminium Keyboard (ANSI)
  bcdDevice            1.26
  iManufacturer           1 Jamesdonkey
  iProduct                2 A3R
  iSerial                 0
  bNumConfigurations      1

In wireless mode:

Bus 001 Device 003: ID 05ac:024f Apple, Inc. Aluminium Keyboard (ANSI)
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               1.10
  bDeviceClass            0
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0         8
  idVendor           0x05ac Apple, Inc.
  idProduct          0x024f Aluminium Keyboard (ANSI)
  bcdDevice            2.00
  iManufacturer           0
  iProduct                1 A3R-U

And `dmesg` shows:

[ 1779.692121] input: A3R-U as /devices/pci0000:00/0000:00:08.1/0000:06:00.3/usb1/1-2/1-2:1.0/0003:05AC:024F.0008/input/input35
[ 1779.749037] apple 0003:05AC:024F.0008: input,hidraw2: USB HID v1.10 Keyboard [A3R-U] on usb-0000:06:00.3-2/input0

In bluetooth mode, the iProduct is "A3R".

Adding "A3R" to non-apple list makes keyboard to work in both wireless
and bluetooth mode.

Best wishes,
