Hello, in attachment you will find patch I use for my udev to fix some strange and stupid errors. This patch works with udev 143 and 145. The earlier versions may need tweaking of patch. Bugs this patch fixes: Makefile* - by default the extra section will not install rules from packages subdirectory. packages directory have useful rules worth installing if an user wants extras. 50-udev-default.rules: - ttyACM modem rule is missing - usb_device rule access mode 664 causes userspace drivers to fail when user is not root. Especially hplip driver for HP printers. - sr devices like SATA CD/DVD burners will fail to work when user is not root. Burning applications will report strange device errors hard to find and fix. k3b application will have Start writing button inactive till sr device rights will not be resolved. In my opinion udev should provide easy, smart access to devices by default. This way someone installing Linux will not end up with 'broken' devices. Security should be tightened at later stage using for example /etc/security/console.perms.d or other security mechanism. Finally if someone needs extra security he/she will fine tune udev rules manually after knowing that all devices are working well with initial configuration. have a nice day, Zbigniew Luszpinski
