Ok, this means you are likely running with secure-boot enabled on a somewhat
older kernel where /sys/kernel/debug (aka debugfs) gets completely disabled.
Can you try (temporarily) disabling secure boot in your BIOS, that should fix
things (otherwise there are other ways to get the descriptors but in my
experience this way is the easiest)

Ok, so as suspected your keyboard behaves as a normal (non-apple) keyboard
using separate (multimedia related) scancodes when using Fn + F1 - F12, in this
case even reporting them on a second interface (likely because the first
interface is implementing the USB kbd boot protocol to make the kbd work inside
the BIOS setup menu).
Which means that your keyboard really should just be handled by a the standard
hid-input driver rather then being handled by the special hid-apple driver.
Now if only it would have not "hijacked" Apple's USB vendor and product id and
would just have used their own then everything would just work.
IOW this is another clone like the Maxxter kbd I added, but the current
clone-detection code is not detecting it (at least not for the first of
the usb interfaces which it has).
Just to make sure I'm not missing anything, can you redo the evemu-record
tests with the switch set to mac mode. And when you gather the rdesc files
can you do that twice too, once in windows mode and once in mac mode ?
Please unplug and replug the keyboard after changing the switch to make
sure that Linux sees the changed descriptors (assuming they change at all).
Regards,
Hans
