Epson ET-2600 works with libusb configuration

Adding usb 0x04b8 0x1122 to /etc/sane.d/epson2.conf works. Is it possible to upstream this, so that adding the line isn't necessary?

$ scanimage --version
scanimage (sane-backends) 1.0.31-198-gbb84652c3; backend version 1.0.31

$ sudo scanimage -L
device `epson2:libusb:001:006' is a Epson PID 1122 flatbed scanner

$ sudo sane-find-scanner -v -v                                                    
This is sane-find-scanner from sane-backends 1.0.31-198-gbb84652c3
