<div>Pete,</div><div><br></div><div>I got home and tried my how-to instructions and sure enough, it didn't work. I then found out why. Since I wrote this how-to they have disallowed renaming and only allow symlinks. So mystery solved. I will be updating the how-to to fix it. In general I am disappointed with this change, because with renaming, I could allocate the known serial devices with a name and leave the automatic names continue to work as normal starting with ttyUSB0 for example. Oh well, maybe it was causing issues that I am not aware. So we just roll with the punches..... as if we have a choice `,~)</div><div><br></div><div>Thanks for pointing out the issue.</div><div><br></div><div>John Vaughters</div><div><br></div>

<p>John,</p>
<p> 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.<br clear="none">

<div><span><span style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;">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.</span></span></div>
