>Description:
I've recently noticed that FreeBSD 5.X and SANE is not working with my SCSI scanner (show above). I thought it might be a SANE problem, but I don't recall having this problem with -any- SANE version on 4.X. I've managed to get older versions of SANE to work a little bit on 5.X, but they seem to work only half the time, or get half way through a scan and coredump.

With the latest SANE (listed above), it doesn't even begin to scan. I can hear my scanner ready itself, and then SANE coredumps and gives me this error in ttyv0:

(pass0:ahc0:0:1:0): Unexpected busfree in Command phase

Any ideas?

Thanks,

Travis Poppe

>How-To-Repeat:

Use FreeBSD 5.X and the latest SANE backends with a SCSI scanner (EPSON ES-800C)
