That's your comment, we have been there.

section 6.3.3

Section 6.3.3 is about an eject method. Also, 6.3.7 which is
about _STA doesn't talk about HID vs PCI devices. I've already
looked into the spec and the acpica implementation and have
failed to find any hint regarding this. If you really want to
help me, I'd need a very specific pointer or a quote of the
spec.
