Ls /dev/ttyUSB* not working

I recently bought a SuzyQable and when I tried to do the command “ls /dev/ttyUSB*” it just says “ls: cannot access ‘/dev/ttyUSB*’: no such file or directory” and I tried flipping the SuzyQable so many times but it still doesnt work. Does anyone know how to fix this?

is the USBA end of the Suzy q attached to the Chromebook or a separate Linux Device? Either way, make sure there is power to the motherboard and Linux device if using

my suzyqable is usb c and i plugged it in to both sides

Both ends are usb-c?

ye but I do have 2 usba ports too

I’m not talking about the ports on your laptop - I’m talking about the cable itself, one end is USB-C and the other end is USB-A. The USB-C end should be plugged into the USB-C port of the motherboard itself (not the daughter board usb-c) and the USB-A end should be plugged into any of the USB-A ports on the laptop

But im using a USB c cable on the SuzyQable not USB A

What cable are you using? Did you make it?

no I’m just using a regular USBC to USBC cable

I tried using a different one but it still didn’t work

What SUZYQ cable are you using?

Regardless, if you are using a regular usbc cable and plugging it into a suzyq board (like this: Chromebook Debug Board / "SuzyQ" / "SuzyQable" adapter for Cr50 / Ti50 | eBay), then use a USBC to USBA cable and plug the USBA end into the Chromebook’s USBA port.

wait let me try that

Nope doesnt work
