Gene,
Tell me more about this udev bug.
I'm not so sure this system even has it. If I check the directory
/dev/serial/by-id is there and has one device in it, and it looks like it is
most likely my device. If my system was affected bu this bug would the by-id
directory not be there, or would it not have any devices in it, or would the
device just not work?
I've a usb tree resembling a weeping willow, over a dozen usb cables
plugged into at least three 4-port expanders, one of which is a 7 port
and its full, so my output from that command shows 2 devices. One is
driving an X10 CM11a to control some lights. And I don't recall what the
other is doing. The x10 stuff has only been running about 35 years. I'm
one of the two authors of the Amiga's ezhome software for x19 stuff.
I've long since forgot the nitty and gritty details of what all I had it
doing.
Whatever you have that did use the /dev/serial/by-id stuff would not be
working if the bug is present. Buster is ok, bullseye and bookworm will
fail and the final trixie is supposed to be fixed. Your stuff is
probably too old to be effected.
Take care & stay well Todd.

No, they are not. The old pc was running Ubuntu 10.04. (Because that was the
last Linuxcnc distro that seemed work with this old pc and it's ISA IO card.)
The new PC is running Debian 12 (installed using an ordinary Debian net install
iso).
The groups the user belongs to on the PC are "adm, dialout, cdrom, plugdev, lpadmin, admin,
and sambashare". The groups for the new PC are "cdrom, floppy, sudo, audio, dip, video,
plugdev, users, netdev, lpadmin, and scanner"
So, I'm not sure, to my unskilled eye, it would seem that "dialout" might be the most
logical possible permission deficiency, but I'm not sure if "dip" might be an equivalent
replacement for that.
Your debian 12 install has the udev bug I sent you a link to the fix already.
It restores the missing two lines that setup the serial/by-id stuff for usb.

What is your MB2HAL load line?
What does lsusb call the dongle?
Are the two PCs in question running the same version of Linux?
