Hi, SCSI Linuxers.
Just curiosity:
I have an NCR 53C825 based hostadapter, and with the 53c8xx driver I get
the following messages short after starting to use the scanner:
[initialization (module)]
Jan 3 13:38:23 infinity kernel: ncr53c8xx : at PCI bus 0, device 13, function 0
Jan 3 13:38:23 infinity kernel: ncr_attach: unit=0 chip=825 base=f4000000, io_port=6000, irq=12

Jan 3 13:39:22 infinity kernel: scsi : 0 hosts.
That's it. The scanner won't even return the slide. I tried all of the
configuration stuff (forcing normal i/o, disallow disconnect,... everything).
Then, I used the other driver (ncr53c7,8xx) and the result was:
[initialization (module)]
Jan 3 15:55:05 infinity kernel: scsi-ncr53c7,8xx : at PCI bus 0, device 13, function 0
Jan 3 15:55:05 infinity kernel: scsi-ncr53c7,8xx : NCR53c825 at memory 0xf4000000, io 0x6000, irq 12

Jan 3 15:55:05 infinity kernel: scsi0 : NCR53c{7,8}xx (rel 17)

Jan 3 15:55:12 infinity kernel: Vendor: MUSTEK^?^? Model: MSF-06000SP^?^?^?^?^? Rev: 3.12
Jan 3 15:55:12 infinity kernel: Type: Scanner ANSI SCSI revision: 01
Jan 3 15:55:12 infinity kernel: Detected scsi generic sga at scsi0, channel 0, id 6, lun 0
[scan did function properly]
I noticed, that ncr53c8xx maps the hostadapter to scsi3, the other
driver maps it to scsi0. Is this a bug, or did I select the wrong driver first?
