Epson 1640SU: no more support since 1.0.32
The device worked up to version 1.0.31
- frontend Xsane
- backend epson2 -- usb 0x04b8 0x010a
After the update from 1.0.31 to 1.0.32, only the error popup "Konnte Scanner nicht starten. Operation nicht unterstützt" in XSane.
Sorry, I don't know the origin message in english. May be "Could not start scanner. Operation not supported" or "Could not start scanner. Function not supported" or similar.
My assumption: changes to epson2 for other Epson scanners have an undesirable effect at a distance.
