No. (if you mean in the udev rule) > Does "one single > parent device" allow the direct parent only? There are a number of parent devices, don't try and match for more than one value per parent device. > Can the attributes belong to the > grandparent or great-grandparent? Yes. I thought the man page was the best guide, but you may find this better:- http://www.reactivated.net/writing_udev_rules.html > > This is one rule I've tried. > SUBSYSTEM=="sound", ATTRS{idVendor}=="0d8c", ATTRS{idProduct}=="0008", > SYMLINK+="USBspeakers" > None of my rules have yielded a SYMLINK. How about the following?:- KERNEL=="controlC3", ATTRS{idVendor}=="0d8c", ATTRS{idProduct}=="0008", SYMLINK+="USBspeakers" GROUP=="sound" or. same thing(?) without trying for two matches from the same parent, and 'trying' to match particular card output:- KERNEL=="controlC3", ATTRS{idProduct}=="0008", ATTRS{id}=="Device", ATTRS{product}=="C-Media USB Audio Device ", SYMLINK+="USBspeakers" GROUP=="sound" > > Thanks for any ideas, ...
