It works with a bit of hacking:

- Disabled some reuquests in Class-specific abstract control
  management functional descriptor, but Linux still sends #x22
  SET_CONTROL_LINE_STATE class request to interface 0.

- Handle the class request handshake by sending an empty IN0

- Interrupt buffer is defined as endpoint #x82 (IN 2) but not actually
  configured in the USB controller.  Seems ok.

- re-enabled stty on every start since initial setting was not correct
