Arduino IDE only listing serial port. No ttyUSB or ttyACM ports.
Hello, I cannot seem to connect my Arduino Nano to my Arch PC. When I go to Tools > Port I only get a Serial port /dev/ttyS0.
I see my Nano listed under lsusb. First was without it plugged in, second is with it plugged in (QinHeng).

Linux arch 5.15.7-arch1-1 #1 SMP PREEMPT Wed, 08 Dec 2021 14:33:16 +0000 x86_64 GNU/LinuxI've installed arduino and arduino-avr-core from the repos. My Arduino version is arduino-1:1.8.17-1 which should be the latest.
I did try it with another PC which ran Ubuntu 20.04 and it does show and I uploaded code without an issue.
Do let me know if there's anything else I need to post. Thanks.

I think I missed this command where you can see I don't have any ttyACM or ttyUSB ports:

Re: Arduino IDE only listing serial port. No ttyUSB or ttyACM ports.
See kernel messages in journalctl while connecting the device.

Sometimes I seem a bit harsh — don’t get offended too easily!
