The epkowa backend also does not support this model at the moment.
There is talk about adding support for it through a /non-free/ binary
only plugin, but there is no schedule yet.
FYI, the epkowa backend is part of Image Scan! for Linux which can be
for scanners and all-in-one devices respectively.
# Eh, yes, I maintain it.

The Perfection V500 does not speak the protocol that the epson backend
assumes. There is just about zero chance that it will work with any
of the other backends that support EPSON devices (snapscan, plustek).
If support for this scanner is added to the epkowa backend, then it
will require a plugin which takes care of the protocol conversion.
Hope this helps,
