Hi guys,

I just connected my genuine Arduino Uno just to see what port it creates,

[ 584.205058] usb 2-2: new full-speed USB device number 2 using xhci_hcd
[ 584.355522] usb 2-2: New USB device found, idVendor=2341, idProduct=0043, bcdDevice= 0.01
[ 584.355526] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=220
[ 584.355529] usb 2-2: Manufacturer: Arduino ( www.arduino.cc )
[ 584.355531] usb 2-2: SerialNumber: 8523535313735130F1F0
[ 584.383481] cdc_acm 2-2:1.0: ttyACM0: USB ACM device
[ 584.384503] usbcore: registered new interface driver cdc_acm
[ 584.384504] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters

I'm using Ubuntu 20.04.1 LTS and I do get a ttyACM0, hope this helps.
