What is the problem?
Octopi not detecting any usb devices
What did you already try to solve it?
Rebooted pi, rebooted pi in safe mode, ssh command lsusb (no USB devices detected other than onboard ethernet)

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ...)
I'm not very good with Linux but I can give more information/logs/etc if you let me know the commands needed to check
