Hi Greg,

I'm trying this patch with my WASD keyboard (https://www.wasdkeyboards.com/).
It's not working, here are the symptoms:

* The keyboard shows as a ums and a ukbd
* When keyboard is attached, I don't see "found consumer control".
* When the Fn key is pressed, I see

Mar  3 23:55:28 goldpeak kernel: ukbd_intr_callback: actlen=8 bytes
Mar  3 23:55:28 goldpeak kernel: ukbd_intr_callback: modifiers = 0x0000

* Similarly, if I then press the media keys (they are sent by combining Fn +
other keys, such as PgUp/PgDn), I see the above 2 lines again.
* When I release the keys, each one triggers the same lines.

I'll try to grab the HID descriptor of the keyboard.
