Fix up BootKeyboard to work under OSX #32

Closed algernon closed 6 years ago

algernon commented 6 years ago

MacOS needs the HID descriptors and the report to have a particular layout. Namely, the descriptors need to have LEDs first, one padding byte, 6KRO keys, and modifiers last. The report must have modifiers first, padding, then the keys.

Tested & verified under MacOS High Sierra:

Can bring up the boot menu.
Can input the password at the FileVault prompt.

When forced into boot protocol mode, still works under Linux. Windows is untested, but should still work.
