[sane-devel] Canon LiDe 210 Genesys backend gone wrong

[stef]

In order to find where your problem comes from, you could run your frontend 
like simple-scan, xsane or scanimage with debug messages enabled. In a command 
shell type (provided you are using xsane):
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL847=255
xsane 2>debug.log

Then the debug.log file will contain messages that should help find what is 
happening.
