Okay. Sorry, I misunderstood. My reading comprehension is really lacking, today.

When I paste the requested two lines into the terminal, the system jumps into running the first line before it accepts the second one. So I'm seeing the entire 50-udev-default.rules document in the terminal. Not sure whether the second line, which isn't being run, was intended to refine the command that does run, or what.

Here, at any rate, is the entirety of my 50-udev-default.rules. Complete with, erm, a typo as the pastebin paste title. Erm. https://pastebin.com/EfLAKAWX

If that isn't what you needed, let me know how to give you what you want and I'll do my best.
