There should be no spaces at the beginning of the line. Also this line=20
will only work if "agfafirm" is the renamed "Snapscan e20.bin" from=20
the windows driver installation.

You shouldn't need this line.

The file permission on /proc/bus/usb/001/* are not set correctly, the=20
backend cannot open the device files through libusb. Either correct=20
the permissions or use the scanner kernel module=20
("modprobe scanner vendor=3D0x06bd product=3D0x2091"). In your first post=20
you used the kernel module, since the scanner was detected at=20
/dev/usb/scanner0.
