[sane-devel] minor: libusb not recognized

[Julien TIERNY]

hi all,
	I have a HP2400 scanjet scanner (USB) and I've just patched the sane source 
code with the genesys backend for test purpose. Everythinng went fine at 
compilation time.
	but here's sane-find-scanner's output:


"
searching for SCSI scanners:
checking /dev/scanner... failed to open (Invalid argument)
checking /dev/sg0... failed to open (Invalid argument)
(...)
checking /dev/sgz... failed to open (Invalid argument)
  # No SCSI scanners found. If you expected something different, make sure 
that
  # you have loaded a SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

I'm affraid sane-find-scanner doesn't try to check the libusb access method. I 
didn't compile the scanner support in linux kernel (I thought I shouldn't). 
Am I wrong ?

What's your opinion ?

thanx, julien
