What is the problem?
finally I have received my Raspberry Pi 4GB and I have installed the last stable version of OctoPrint.
Since the first start the webcam work immediatly but the usb connection with my Artillery Hornet don't work e the system do this error: "SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)."
Octoprint has automatically set these connection values:
Serial Port: / dev / ttyACM0
What did you already try to solve it?
I tried to restart the system, I tried disconnecting the webcam from the USB socket leaving only the 3d printer, I turned the 3d printer off and on again, I tried to swap the USB ports, I also tried to vary all the baudrate values but nothing changed.
I have change the USB cable.
Have you tried running in safe mode?
Did running in safe mode solve the problem?
No, I have same problem.
