I've experienced issues with AIs in the past using USB 3+. What interface is it and what motherboard?
motu m2, asus x570-plus tuf gaming wifi
Hmm... on paper there shouldn't be any issues. In the BIOS is there a setting for legacy USB devices? If so turn that on/off and retest. It might also be with updating your BIOS.
update, just used a usb c to a adapter and tried a different port and it worked??!?! the port isnt damaged cause it draws power and it definitely is supposed to transfer data, any ideas?
Is it now on a usb 2.0 port? Sometimes, some device "don't like" usb 3.X
usb c 3.2 gen 2 to a usb a 3.2 gen 1
Does anything show up in dmesg output when you plug it in the original way?
i'll check, what should show up
Basically, anything. The most basic step is seeing if your computer knows the device has been plugged in. If you see anything new in dmesg it means there's a data connection going on and you can read the output and diagnose from there. If you don't see anything after plugging, it's probably a hardware issue with the port.
use lspci to find out if a module (aka driver) is running and google the pci id's if there isn't one. the man page or google can show you how to do this.
alternatively, you could use dmesg to show you what happens (if anything) when you plug/unplug your device. if nothing happens then you'll still need to google your device's pci id's. to see if there's a module for it.
Are we 100% certain the USB-C port is connected?
power transferred...?
Derp, I can't read apparently
Do any other devices work on the port?
That's the thing ! It's not linux specific.
How it works :
USB 1 and 2 use a set of 4 pins. It can only use those 4pins to transmit data.
USB 3 uses 9 pins : the 4 original pins and 5 more pins. It is backwards compatible with USB 1 and 2 because it can only use those four pins instead of the full array.
USB-C, however, uses 24 pins (2*12 pins to be exact). However, what makes no sense, is when using a USB-A to USB-C cable it does work only in one direction : from USB-A to USB-C.
But rest assured, you are not alone onnthis issue. I've had it, even when I did not want to tranfer data but just power : it does not work, whether on Windows or Linux...
