Hi Marco,

To comment this driver you add '#' before 'escl', in the file 
'/etc/sane.d/dll.conf'.
device `escl:http://127.0.0.1:60001' is a Epson XP-4100 Series (USB 1) 
flatbed scanner

To comment this driver you add '#' before 'imagescan', in the file 
'/etc/sane.d/dll.d/imagescan'.
device 
`imagescan:esci:usb:/sys/devices/pci0000:00/0000:00:12.2/usb1/1-6/1-6:1.0' 
is a EPSON XP-4100_Series
