Hidapi for processor

[boredland]

Hi there,
when handing over a scanjob from spreadpi to processor, somehow the processor calls for the hidtrigger-plugin and therefor hidapi. I'll now try installing that one to get this out of my way, but why does it call for it? If I'm right its quite unnecessary...
Yours

Remove hidtrigger from your config in the processor.

[boredland]

Well.. that would be to easy. It isn't in my config:

    logfile: ~/.config/spreads/spreads.log
    convert_old: yes
    verbose: yes
web:
    mode: processor
    standalone_device: no
    debug: yes
    postprocessing_server:
    project_dir: ~/scans
    port: 2060
driver: dummy
plugins:
- scantailor
- tesseract
- djvubind
- pdfbeads
- web
device:
    upside_down: no
    flip_target_pages: no
    focus_mode: autofocus_all
    single: no
    depends: 0
    parallel_capture: yes
    test: 1337
    super: foo
tesseract:
    language: deu

Are you sure it's not on the spreadpi instance that there is hidtrigger ?

[boredland]

Yes I'm sure:

I installed hidapi, now it's mocking me with a warning

spreadsplug.hidtrigger: Initializing HidTrigger plugin
spreadsplug.hidtrigger: Could not find any HID devices.

followed by doing nothing. The Scanjob arrives a the processor, where I can trigger postprocessing again, followed by the following output:

When viewing the scantailored files, everything seems fine. Sadly no generated pdf (perhaps the rmagick thingy pdfbeads is telling me?).

EDIT: the pdfbeads rmagick-thing has no effect, the book.pdf in the "out" folder in the working directory is working fine. Seems to me there are two problems:
1st: The Button for pdf-download on the webinterface of the processor has no effect.

2nd: I always thought at least the output-file(s) get delivered back to the shooting-devices interface, since thats the one users are facing after they started a postprocessing job. Am I wrong and this isn't implemented or is it just not working for me? Or do I need to start the raspberrys spreads not in "standalone", but just in scanner mode?
