Anyone have luck getting mini connected to octopi. I am running it on a raspberry pi 4. What /dev/tty* port should I add for manual port connection.  I tried. 2 USB cables and still can't connect 

Best Answer by Gordon W:

Which USB port are you using on the Mini? You need to connect to the mini (or is it micro?) USB port and not the one the USB stick goes into. Octoprint should find the port automatically.

Here is error from octopi terminal when trying to connect. 

 

 
Changing monitoring state from "Offline" to "Detecting serial port" Serial port list: [] Changing monitoring state from "Detecting serial port" to "Error: Failed to autodetect serial port, please set it manually." Failed to autodetect serial port, please set it manually.

Don't have a mini but there are several posts on this board saying that it works.

Too late to edit post above but the port you are looking for is /dev/ttyACM0

Thanks Gordon-W.   I was wondering why it was using old school usb-A to usb-A cable.  I didn't even realize there was a micro usb port there.  I connected it and it found /dev/ttyACM0 right away.  Thanks for the help.  greatly appreciated.
