Hi, Please see the previous discussion about this issue on bug 665:
http://sigrok.org/bugzilla/show_bug.cgi?id=665 In short, there is no rules file we can supply that will work for all users on all distributions. My proposal was that we remove the rules file entirely, and replace it with a machine readable list of VID/PID pairs that libsigrok is interested in, along with a script to generate udev rules files from this as well as similar things for other systems, e.g. I think there is some list that has to be provided to Android for it to allow PulseView to use USB devices on that platform. I did some work on this about a year ago: https://github.com/martinling/libsigrok/commits/remove-udev-rules I believe someone else implemented a script to generate things from this too, but I forget who it was or where they published it.
