What exactly does 0x06 mean? Flash led? Isn't there some kind of
"bright-led" "5V,12V,24V" settings available? I mean I want to be able
to change the brightness.

And what is the PMU packet? One Byte, two byte, value 0x2342?

Please point me to a FM about adb.


Keep it simple & stupid, use what's available.
