Thank you for your help,hotplug worked just fine.
However i have a little question:
in the document you linked there was an example foo.usermap file with
hard coded PID and VID in it.
However I only know a VID for sure.I would need to use some kind of
wildcard, i.e. match any usb device with this PID, no matter what PID
it has.
Is there such a way? or should i create one file for each peripheral?
Thank you again for your help!
