I suspect why yours worked is that you renamed from dsp* to dsp so if
there was a conflict it went away by doing that. I tried doing similar
but I was naming eth0 rather than eth. I should try experimenting some
I do think udev could be improved though. How hard would it be for
udev to do "I will give existing devices their name they have used
previously and then set up names for new devices"
