     Hello,

     could you add :
export SANE_DEBUG_SANEI_USB=255
     before running scanimage -L as root ? I have seen usb failing 
sometimes on setting alternate endpoints. Which was solved by compiling 
SANE with the old libusb (not libusb-1.0). With this debug level we 
should have more information about it.

Regards,
     Stef
