[sane-devel] Pls help SANE avision backend / Mac / HP

[Brian]

Dear SANE developers,
cc: Mike avision.conf maintainer,

On my laptop, sane-find-scanner finds the scanner, but scanimage -L will not

Running SANE on Mac OS 10.6.  
read the old message archives at http://www3.sane-project.org/old-archive/2001-07/0225.html
read the old message archives at https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/270185

Proper files are found, no error messages.
I ran as root, so permissions are not the issue.
I have all backends disabled except the one that advertises to work for my HP ScanJet 5300C
Tried running with stock avision.conf
Also tried uncommenting the USB vendor code line in avision.conf because the vendor and product codes match mine.

It just hangs.
After about 4 hours of debugging, I'm stuck.
Please help!

Here is a terminal dump:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

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

  # Your USB scanner was (probably) detected. It may or may not be supported by
