For example: /sys/class/tty/console/dev Without these dev entries udev won't work. They should be automatically generated by the device drivers. --- Roman Duka wrote: > > If you go into the test directory, after installing udev, and run the > > test.all script as root with the 'add' paramater: > > test.all add > > > > Do you see new nodes show up in /udev? > > > > If not, something is not installed properly. > > > > If there are nodes, great, it's working :) > > > > No Greg I don't get anything in /udev the script calls udev and there > are no error messages or anything, however /udev is still empty I need > to ask you a few questions: > - I compiled udev on Linux running kenel 2.4.20, however I am trying to > get udev working on kernel 2.6.0 which has support for hot-pluggable > devices and module loading/unloading enabled.
