February 4, 20242 yr Hello i use octoprint on my orange pi with armbian. Now i want to get multiple octoprint instances. so i use docker. i found many tutorials in the web The problem: i need to set udev rules for my usb connection of each 3d printer. I found many tutorials too. But my quesstion: can i detect the usb infos from the usb connection, when i use a usb port and connect the printer? Does udev_rules works with passive and active usb hub? Cause i would prefer to use a passive usb hub thank you
February 18, 20242 yr Instead of connecting to /dev/ttyUSB0,1,2,3.. or /dev/ttyACM0,1,2,3... there are links in the /dev/serial/by-id/ and /dev/serial/by-path/ folders with links that are constant, relative to the USB adapters inside the 3D printers.
