Like I said, it's damned difficult to come up with something. If you

I do have a better idea: Go back to the way it was when you could
use udev to permanently assign names to interfaces :-).
As you have just shown it is impossible to get it "right" but
before they "fixed" it, you could at least get it to remain
consistent with the udev rules.
Stop trying to solve impossible problems.
I have several questions around the naming convention.
My usb wireless adapter is named wlp3s0u2, hence the naming convention
is saying the adapter is usb device 3. I do have 3 usb devices
connected. Two of the devices are usb 2 and the adapter is usb 3, hence
when the device enumeration is done to determine what exists, what
controls whether usb 2 devices are enumerated first , is it software or
the motherboard? Assuming the naming convention is based on enumeration
which it may not be given that, I have 2 usb 3 slots on the front of my
machine and, if on the running system I unplug my wireless adapter and
plug it into the second slot, when the system recognizes the device
again the name changes to wlp3s0u1. Also I have 2 usb 2 slots on the
front of my machine, and if I do the same thing to my adapter and unplug
it from the usb 3 slot and plug it into the second usb 2 slot the name
changes to wlp0s19f2u3, hence what does the naming convention actually
represent?
As I said above I have 3 usb devices, the other 2 are a keyboard and the
transmitter for my wireless mouse. How do I find what the naming
convention for those two devices is, in terms of what they are actually
named?
Lastly, if I plug a flash driver into the usb 3 slot where my wireless
adapter was what name does it inherit and how do I find out?

Steve
