Created attachment 872077 [details] proposed replacement for libftdi udev rules Description of problem: libftdi provides /etc/udev/rules.d/99-libftdi.rules, which doesn't work as intended on recent Fedora releases (and probably EPEL7): 1) The rules use GROUP="plugdev", but the plugdev group no longer exists. (Regression from fix of bug #517773?) That should be replaced with TAG+="uaccess" 2) The rules file shouldn't be in /etc/udev/rules.d, which is for user-added rules. It should be in /usr/lib/udev/rules.d 3) The numeric portion of the rules file name needs to be less than 70, so it runs before /lib/udev/rules.d/70-uaccess.rules I recommend replacing the existing file with the attached file as /lib/udev/rules.d/69-libftdi.rules. (That will also resolve bug #1015289.)
This will be fixed in 1.1 (committed to git now) but the new version will need some coordination with the dependent packages
