Hi, I now only have one config file /lib/udev/rules.d/50-udev-default.rules I tried udevadm test /sys/bus/hid It complains : udev_device_read_db: no db file to read /dev/.udev/data/+subsystem:hid: No such file or directory Is it a bug ? It needs default groups. Are all needed ? I seem to have the minimal groups list. root:x:0: bin:x:1: kmem:x:3: tty:x:4: tape:x:5: daemon:x:6: floppy:x:7: disk:x:8: lp:x:9: dialout:x:10: audio:x:11: video:x:12: cdrom:x:15: Thanks in advance. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
