What are you trying to accomplish here? sane-find-scanner just lists the
devices it finds.

On 5.3, I don't have to use usbd at all. The device node is created by
devfs (on 5.3). You might have to do it manually on 4.x?. I use
devfs.rules to make the scanner device available to a group usb, of
which I'm a member, and that's it. Sane can use the scanner.

For the record, my dll.conf looks like this:

--------------------------- dll.conf -------------------------------
# Load the epson backend.
epson
--------------------------- dll.conf -------------------------------

And epson.conf contains just:

-------------------------- epson.conf ------------------------------
usb /dev/uscanner0
-------------------------- epson.conf ------------------------------

I usually do it the other way around. I keep the USB cable plugged in,
and connect or disconnect the power to the transformer, because the 1650
doesn't have an on/off switch.

Do you see anything in dmesg output after you plug in the scanner?
