Opinions about using USB serial numbers

I have a lot to do with systems using many USB devices of the same
Currently device are named acording to their probing order.
That result in the problematic that device names can change after
reboot or replugging in different order.

I would like to add functionality for creating alias devnodes
including the serial numbers (if the device has one setup).
E.g. for a ucom(4) device you will get /dev/ucom0 and ucom.serialnumber.
If the device has no serial numer there will be just /dev/ucom0
as befor.

Another solution could be to create the nodes in a tree form:
That would work for devices without serial numbers too, but I
personally dislike this way.
