DJI Mic Mini Monitor: decoding the receiver's USB status stream

DJI Mic Mini Monitor reads transmitter battery and charging state from the receiver's USB status stream on Windows. Its Python reader uses WinUSB, while protocol notes describe MI_06 bulk endpoints, frame boundaries, CRC checks and status offsets; the author reports checking those details against a local receiver.
