These scanners are fairly limited, only supporting a couple of modes and resolutions, and always scanning full width. The backend supports missing modes (binary, grayscale) and intermediate resolutions in software, but provides only minimal scan area controls. See
This backend may support other scanners. If physical inspection reveals an Epson chipset, please contact the author for instructions on collecting a USB trace under Windows to verify.
.SHOPTIONS
A limited effort has been made to expose the standard options to the API. This allows a frontend to set resolution, color mode, and choose the ADF setting. The epjitsu backend supports the following basic options for most scanners:
is used to tell the backend how to look for scanners, and provide options controlling the operation of the backend. This file is read each time the frontend asks the backend for a list of scanners, generally only when the frontend starts. If the configuration file is missing, the backend will not work.
Requests backend to search all usb buses in the system for a device which uses that vendor and product id. The device will then be queried to determine if it is a supported scanner.
Some systems use a kernel driver to access usb scanners. This method is untested.

The only configuration option supported is "firmware /PATH/TO/FILE", allowing you to set the location of the firmware file you have extracted from the Windows driver.
