Ok. I haven't tested FreeBSD with older scanners for some time so here
are my results with Mustek SCSI scanners (symbios-compatible 810 SCSI
controller, FreeBSD 5.0, sym driver):

Scanner                                        1.0.12         your patch
------------------------------------------------------------------------
ScanExpress 6000 SP (relatively new)           ok             ok
Paragon 1200 SP Pro (relatively new)           detected,      same    
                                               but timeout
Paragon 12000 SP (older)                       not detected   not detected
Paragon 12000 CX (stone age three-pass)        not detected   not detected

If I try to use the "ncr" driver instead of "sym", FreeBSD doesn't
even boot. With a Tekram 315 controller the results are the same as
above.

So your patch is ok but FreeBSD 5.0 is unusable with older Mustek
scanners on at least these controllers. The scanners work just fine on
Linux.

The timeout with the Paragon 1200 SP Pro occurs when the lamp warms up
that warm-up can take upto about 70 seconds. With Linux and the later
SANE versiosn that's not a problem but FreeBSD seems to ignore the 120
seconds timeout. When the lamp is warm, the scan starts ok but sounds
horribly and never finishes. No idea why, but this also happens
without your patch.

The "not-detection" looks like this: Booting FreeBSD stops and the
scanner LED starts blinking. Looks like the scanner gets sent an
invalid command from the kernel. If I turn off the scanner, FreeBSD
boots. When I run "camcontrol rescan all", the scanner blinks again
and camcontrol freezes.

If I remember correctly, the old scanners worked once with FreeBSD. So
maybe 5.0 has broken the SCSI system?

Bye,
  Henning
