It does but only one such entry is supported.

A simpler way would be to tune the hard-coded lists of supported
scanners (in backend/epson_usb.c) and modify the *.desc files to follow
suit.  Oh, I see that both backends use the *same* file and that it is
generated by a script from epson2.desc these days.  That didn't look
right at all so I pushed pu/epson-epson2-usb-split.  Please have a look
and consider merging this.

Hope this helps,
