Is this a multi-function printer/scanner device?
If not, I really don't know how this would happen...
Yes the Epson CX3650/CX6600 is a multi-function printer/scanner device.
Can you attach the output of /proc/bus/usb/devices with the device plugged in?

This should work just fine, please contact the SANE people, as the error is on
their part. The scanner should just bind to the scanner interface, which the
usblp driver is not bound to.
