Sorry joerg, you already asked once and we didn't comply :-)

Actually I guess this topic doesn't even belong in the "problems" thread either, as the h-e-n part is mostly solved now. We are more into redirecting pulseaudio and/or client software and such...

I think I'll create a new topic dedicated to this particular use case (the "what" and "why" rather than "how"), to end the OT here, and maybe find other interested users who are not following this one.

I have just one last question about h-e-n, maybe covered elsewhere :

I understand h-e-n is a GUI for a bunch of scripts which handle the actual USB host stuff. Are these documented somewhere ?
I would like to know if it is possible to automate the select-speed/apply-power/enumerate steps in a script before launching other software...

Thanks,
fp
