Present worry is getting reliable data to replay in the first place. As I
said usbmon truncates bytes and I have several observations to believe
that wireshark data is not reliable - even the endpoints it claims to have
talked with are not present in lsusb output of the same device. Its export
is totally buggy as well.
Hence I'll try binary interface of usbmon next time around which will be
(hopefully) more reliable.

At present, if anything other than 'Input/Output Error' or 'Timeout'
occurs I'd consider that as progress! I don't think 'read' is a problem
itself and it's unlikely that I'll miss the data that is returned - of
course I can confirm that only after going past these errors.
