[sane-devel] Epson DS-530 Backend

[Anthony Sokolowski]

Hi Olaf,

Thank you for the clarification.

Product ID for the DS-530 is 0x0155

I tried adding this to epsonds.conf as per your instructions and epsonds 
man page. scanimage -L found no scanners.

scanimage -L works now only after running the imagescan install script 
from Epson.

Regards
