Hi Matthias,

I don't use DF on the desktop but I just checked /etc/sane.d on my
OpenBSD 5.7 with the following version of sane-backend

predrag at oko$ pkg_info sane-backends
Information for inst:sane-backends-1.0.24p2
 
Quick greping reveals that the specific product is missing. 

predrag at oko$ grep 0x04a9 *

If I was you I would try editing canon630u.conf which is on your machine
probably located in 

/usr/local/etc/sane.d/

usb 0x04a9 0x2206

After you add it reboot the machine and give it a try. If that doesn't
work try editing canon_dr.conf with the same line and reboot.

I checked sane-backends page and your scanner indeed appears to be
supported

http://www.sane-project.org/sane-backends.html#S-CANON-DR

IIRC that is one of those cheap scanners without power supply just using
USB to power up. Those are really iffy on any system. For the record 
I have been using Epson Perfection 1670 which requires firmware for the
past 8 years on OpenBSD and I couldn't be happier. 

Best,
