Dream on. 8) USB is not a simple, friendly interface like the adverts want you to think. It's fiendishly complex, and still less than completely designed. The 'ugen' driver is a catchall which will claim a device that nobody else has claimed. It supports nothing, basically. Go the the USB website (www.usb.org), hit the developer's section, and start looking for documents related to scanners. You should probably also talk to HP and ask them for scanner-specific stuff, because the generic scanner class is almost certainly only going to specify the basics of talking to the scanner; there are going to be commands and procedures which are unique to your device. -- \\ 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-current" in the body of the message
