Microsoft Natural Ergonomic Keyboard 4000 issues

[axeld]

When pressing the F-lock key, its LED goes off, and the F-keys don't work anymore - as expected. Unfortunately, it doesn't go back anymore, the LED is not light again when you press the F-lock key again.

Also, none of the extra (media, ...) keys seem to work.

Here is a description of its HID report:

This has been fixed with Michael's work on the HID.
