Well, it looks like your systemd services come from packages "system-config-printer" and "cups-pk-helper", and I have none installed. You can try disabling or uninstalling them and see if it makes any difference.
Other than that, I'm out of ideas, sorry.
I tried removing system-config-printer but it made no difference - but thinking about it the scanner operations should not be affected by the print side of things. I also tried blacklisting the usblp module and that also made no difference. I am beginning to wonder if my problem is a bug in sane-backends - I have been searching for bug reports and it is possible that reports such as this one: https://alioth.debian.org/tracker/index.php?func=detail&aid=314021&group_id=30186&atid=410366 may be related. I have seen other reports from Fedora indicating that there are recent problems with scanners not working whereas previously they were working out of the box. In fact my scanner was working fine when it was connected to a Fedora 16 system until very recently - since I now exclusively use arch I need to have it working in arch as it is connected to my main machine. I will continue to search bug reports and then if I don't see any that are specific to my device I will file a bug, possibly upstream on the sane bug tracker. -- mike c
