What do you get instead?
I took a look on your 'tree' and it has only one interface.
So, if you match with the SYSFS{serial}="304087" there should still
the tty be created.
Matching any device along the chain of your "node-device" with a rule,
will still create only the "node-device", nothing else.
Maybe I'm a bit confused and if I get the subject completly wrong
please tell me :)
