[sane-devel] Fail to detect the SCSI card

[Stephen Liu]

Hi folks,

I have been trying hours failing to make following
scanner to work again.  Previously It worked on RedHat
8 on this box

Alfa SnapScan 310 connected to a ISA SCSI card
FedoraCore2
=================

This box has another removable hard drive running
WinME.  This scanner is still working on WinME


Test performed as follows;
=========================
# sane-find-scanner

  # No SCSI scanners found. If you expected something
different, make sure that
  # you have loaded a SCSI driver for your SCSI
adapter.

  # No USB scanners found. If you expected something
different, make sure that
  # you have loaded a driver for your USB host
controller and have installed a
  # kernel scanner module.

  # Scanners connected to the parallel port or other
proprietary ports can't be
  # detected by this program.

The driver is there

No scanners were identified. If you were expecting
something different,
check that the scanner is plugged in, turned on and
detected by the
sane-find-scanner tool (if appropriate). Please read
the documentation
which came with this software (README, FAQ, manpages).

Please advise whether I have missed some points
