Hello,
what SANE version do you use ? What is the frontend program used ?
Try to enable logging traces so we can have an idea of what is
going wrong. Suppose the frontend you use is xsane, in a command shell type:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
export SANE_DEBUG_GENESYS_GL841=255
export SANE_DEBUG_GENESYS_GL843=255
export SANE_DEBUG_GENESYS_GL845=255
export SANE_DEBUG_GENESYS_GL846=255
export SANE_DEBUG_GENESYS_GL847=255
export SANE_DEBUG_GENESYS_GL124=255
xsane 2>debug.log
Then send us the debug.log file (compressed to minimize size).
I have also found that sometimes, disabling usb power saving a
kernel level helps.
