Hi all, I am a newcomer here. I previously use the build-gnuradio script to get a modern version of gnuradio and UHD. The script did a great job. But I guess some (small) updates are needed. One is related to udev conf. I saw the warning while booting my OS (Fedora 14): Starting udev: udevd[584]: BUS= will be removed in a future udev version, please use SUBSYSTEM= to match the event device, or SUBSYSTEMS= to match a parent device, in /etc/udev/rules.d/10-usrp.rules:3 I searched the web and this page[1] suggests that substitution will work. But I’m not sure. Another is with the latest Fedora 16. I plan to upgrade my OS in a few days(maybe just tomorrow), and the current script only supports up to Fedora 15… [1] [GnuRadio installation | The SDR Blog](http://sdrblog.wordpress.com/gnuradio-installation/) – alick Fedora 14 (Laughlin) user [https://fedoraproject.org/wiki/User:Alick](https://fedoraproject.org/wiki/User:Alick) ---

On my Gentoo system, I also get the Udev errors, I don’t know where excacly this comes from (but it is annoying). It might be part of the build system of the UHD driver, since I haven’t tried using the script. Best Paul 2011/12/2 Marcus D.

But it sounds like UDEV is migrating to a new syntax for entries in the config files under /etc/udev/rules.d, and that it’s issuing preemptive warnings that the old syntax will stop working at some point. I’m not sure if the UHD “make install” now also puts in the rules in /etc/udev/rules.d, if it does, I need to coordinate with Josh I guess.
