It doesn't even support IRQs, so it operates in polled mode. This means your CPU is 100% busy while scanning. There IS a driver for Linux, but the card is still terrible. Solution: Buy an NCR810 based card for $30, and find a 50 pin miniSCSI-miniSCSI cable instead of the 25 pin, and don't look back. :) According to the SANE port (Scanner Access Now Easy) documentation, some Mustek scanners do not support disconnect/reconect, so you almost have to have them on their own SCSI bus. The 1200LSes I have all support disconnect/reconnect, and the one in my den also has a CD-R and CD-ROM on the same SCSI chain, so you don't need that silly single target card. Later...... <Doug> P.S. I have 3 of these cards if anyone wants one. :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
