Last change on this file since 6cb58e6 was 6cb58e6, checked in by Vojtech Horky <vojtechhorky@…>, 15 years ago

Virtual USB layer rewritten

Major changes include

  • IPC sends whole transfers (not transactions)
  • separate transfer queues for each device in host controller
  • possibility to return NAK from virtual device (handled by HC)
  • better implementation of callbacks for non-zero endpoints

Still missing

  • communication for some transfer types (bulk)
  • face-lift ;-)
  • documentation
  • Property mode set to 100644
