OMS fingerprint module: reconstructing USB communication for a Linux driver

The OMS fingerprint module investigation reconstructs USB communication with the 33a7:2388 match-on-chip sensor and implements it as a libfprint driver. Its notes describe USBC transport acknowledgements, EF01 frames, checksums and enrollment and identification responses; the author reports successful hardware enrollment and verification.
