I get no output, unless it's writing some log file somewhere I don't 
know
about.

Apparently, the rpm I installed does not have debugging enabled.
(And this is the one I can't recompile. :(  )

[root at mofo xsane]# ( export SANEI_DEBUG_SANEI_SCSI=255; export 
SANE_DEBUG_HP=255; scanimage -d hp:/dev/sg3 | xloadimage stdin )
scanimage: open of device hp:/dev/sg3 failed: Invalid argument
stdin: unknown or unsupported image type
[root at mofo xsane]# sane-find-scanner 
found SCSI processor "HP C2520A 3644" at /dev/sg3
found SCSI processor "HP C2520A 3644" at /dev/sgd
   # Your SCSI scanner was detected. It may or may not be supported by 
SANE. Try
   # scanimage -L and read the backend's manpage.

   # 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.
