Greetings all;

/dev/serial/by-id has not been created for quite some time. The arm folks have had a patch script for quite a while but it has not been fixed in debian that we know of. I have 4 identical banana pi's, 3 of which seem to work, but the patch has not fixed the 4th on for some unk reason.

When a serial device is plugged into a usb point, /dev/ttyACM# is created on all 4 machines, but /dev/serial/by-id entries are not. Some of the 3d printer stuff uses that by-id thing to separate printers plugged into the same host, and the lack of a /dev/serial entry kills the 3d printer drivers.

Can anyone give us a hint as to when this will be addressed?

Hi Gene,

The subject suggest that it's "60-serial.rules" which is broken. This would be a udev rules file.

If you know the contents of the patch, couldn't you just create your own rules file which implements this patch? Is there any particular reason why you need to wait for Debian to make the change?

biggest reason is to prevent its (60-serial.rules) being overwritten by an update if apt discovers we've overwritten its broken defaults, or if replaced, is replaced by an even better version. This bug has caused all users of 3d printers that have replaced the marlin gcode interpreter in their printers with the faster, more capable klipper, which I'd estimate is about 50% of the serious 3d printer users. I have 4, supposedly identical banana pi's, 3 of which this patch fixes, but the 4th one must have something blown, it does create /dev/ttyACM0 but does not create the matching /dev/serial/by-id device when a printer is plugged in.

All 4 are uptodate as of yesterday as armbian bullseye uses your arm64 repo's. That and I have little understanding of how udev works, so I'll let the real udev coders handle that. I am 1 user with several machines, an update to that file that fixes this bug, would fix everyone.

Take care & stay well Darac.

Cheers, Gene Heskett.
