"Twain" is the software interface between the scanner-specific drivers and the user application. SCSI scanners are usually processor target devices, and their communications protocols are all proprietary. There is no indication that this will be any different for USB; there's certainly nothing that leads me to expect a standardised command set or data format(s). -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
