I can confirm that this problem also occurs with the Epson Stylus Photo RX595 all-in-one.
In my case, lsusb gave: Bus 004 Device 007: ID 04b8:083c Seiko Epson Corp. So, the magic line in /etc/udev/rules.d/45-libsane.rules was: # Epson RX595 SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="083c", MODE="664", GROUP="scanner" Scanning now works perfectly, though sane detects the scanner as something else $ scanimage -L device `epkowa:libusb:004:007' is a Epson PM-A840 flatbed scanner -- [wish] support for Epson Stylus DX-4050 scanner https://bugs.launchpad.net/bugs/163309 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
