I'm having problems with my Leonardo based keyboard emulator.
It's working fine inside MacOS but not at the FileVault login screen (which comes before my OS is even loaded)
I'm using a modified USB Core/Description that only loads the HID profile, so no serial device connection is active.
I tried to change the vendor and product ids to match the working Apple Keyboard without success...
This is probably related to the drivers on the Mac side, but how can I make the Leonardo act even more like a keyboard...?
Thanks for any help...
