Octoprint does not connect via USB, only works with the printer turned off
What did you already try to solve it?
I used 4 different USB cables
I tried to connect a usb cable without the VCC wire connected
I changed the memory card 2 times
I rewrote the motherboard bootloader
I reinstalled the motherboard operating system (Marlin)
I tried to use clean operating system and install Octoprint manually
I checked all the connectors
I changed the Raspberry's power supply to 5v - 3A
When typing dmesg the following USB error appears:
usb 1-1-port5: connect-debounce failed
Additional information about your setup
Marlin 1.1.7 (This is my original, I don't know if there are any firmware prerequisites to run Octoprint)
