 Curiosity is the name of the game. Now you have me curious. I will check it out and report back, probably this weekend.

John,
 
   Please don't lift a finger on my account: you've been a great help and I've got what I need now. Most especially don't add new sources of USB pain on my account. :-) Good old UARTs! But if I've created an itch that you can't resist scratching we'll be eager to take advantage.

  I will provide some context to the solution I wrote. I wrote it about 5-6 years ago and it was on TinyCore Linux and I was probably doing all  processes as root. So it may also just be that I never bothered with the security/permission side of the equation and therefore did not run into the same problems you are encountering. I do not actually use this solution anymore, but I do have a couple OrangePi Zero that are still using  USB serial ports, maybe it's a good time to try the UDEV again. I haven't because I have these sensors slated to be replaced with direct UART.
