udev_rules with extern usb-hub?


Recommended Posts

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

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.
