Here is a bug reported by a Debian user of sane. The error message is
quite difficult to understand. It would be good to have a clearer
message.

If the access permissions for the physical device are inadequate, scanimage
fails with a very misleading error message:

$ scanimage -d hp:/dev/scanner --resolution=300dpi --mode Color > /tmp/ol.pnm
[sanei_init_debug]: Setting debug level of hp to 128.
[hp] attach: opening /dev/scanner
[hp] attach: open failed (Invalid argument)
[hp] attach: opening /dev/scanner
[hp] attach: open failed (Invalid argument)
scanimage: open of device hp:/dev/scanner failed: Invalid argument

When the permissions on /dev/sgc were changed to 666, the problem
went away.

Please change the error message to indicate the nature of any problem
encountered.
