I edit the snapscan.conf file and add the firmware copied from windows driver. Then i try 'scanimage -L', it found the epson 1270 scanner in 'libusb:005:006'. But when i try to scan the photo, it failed.
>From the debug log file, it seems something wrong when download the firmware. The firmware file is copied from windows driver after i installed it.
