usage with scanbd: invalid argument when script is executed directly about sane-scan-pdf HOT 7 CLOSED

I have a Fujitsu S1500 as well. I'll install scanbd here and see if I can reproduce.

I'm assuming you've configured scanbd as recommended?

from sane-scan-pdf.

I followed several instruction pages to configure scanbd since the original README (https://github.com/mdengler/scanbd/blob/master/doc/README.txt) is a little dated.

The major difference to the instructions in the link is that I use systemd (scanbm.socket) to listen for requests to the scanner in the network instead of inetd/xinetd. But since that part seems to be working (I can scan pressing the button or access the scanner through the network from a different machine with Xsane) I started testing with calling scanadf directly.

Thank you for looking into it.

I'm on Fedora but these arch instructions seem to be pretty up to date, and use systemd. Does this sound something like your local configuration?

@nyn44e I tried to install scanbd but was unsuccessful (compile error I don't have time to resolve).

That being said, I've committed c892202 to the repo, which allows an empty device argument i.e. --device "". With an empty device argument, no -d parameter will be set for scanadf. If your evaluation of the problem is correct, this should allow you to move forward.

BTW, on my machine, not specifying any -d argument causes a long pause (I believe while scanadf is trying to enumerate devices) and also a crash in scanadf. But let me know if it works for you.

Those are pretty much the configuration guidelines I followed for scanbd.

Thank you very much for the new commit. That fixed it. It will now scan instantly, whether I press the button or just execute the script. Thanks a lot!
