     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.
