Hi,

I'm the owner of a similar model (V330 Photo). It works perfectly (slide module, high-resolution scans, etc.) but only with the proprietary Epson drivers.

You can download and install Epson drivers:

https://epson.com/Support/Scanners/Perfection-Series/Epson-Perfection-V800-Photo/s/SPT_B11B223201?review-filter=Linux#drivers

Regretfully, the installation script fails to register the driver at least in the modern (after 2017) RPM-based distros (mine is Mageia 7/2019).

To fix this you should determine the <vendor-id> and <product-id>:

sane-find-scanner

It outputs something like:

found USB scanner (vendor=0x04b8 [EPSON], product=0x0142 [EPSON Perfection V33/V330]) at libusb:002:006

Then the scanner should be registered (from root):

iscan-registry --add interpreter usb 0x04b8 0x0142 /usr/lib/esci/libesci-interpreter-perfection-v330

After that, everything works like a charm.

Hope this helps.

Best regards,
Yuri
