can't find my ethernet controller device
I'm trying to use an ethernet cable, connected through a usb adapter. I'm failing at the first step in the wiki, which is to find the device and kernel modules for the ethernet controller.
lscpi -v | grep Ethernet prints nothing.
Full output of lspci.

If it's connected via USB, not PCI, then you need to use lsusb, not lspci.

Re: can't find my ethernet controller device
USB isn't PCI, so lspci will likely not list any USB devices. You have a typo in your first command, btw, it should be lspci, not lscpi. You can use 'lsusb' from the usbutils package to list all usb devices.
But what is your actual issue? If it gets assigned a network device, it's working, I assume?

Re: can't find my ethernet controller device
Ok thanks. How can I find the kernel module containing the correct driver then? I don't see anything that looks like the 'Kernel driver in use' field from lspci.

Re: can't find my ethernet controller device
@twelveeighty thanks, no it isn't working, and I don't know why. I was following the wiki Ethernet page and trying to check the kernel modules are loaded.

Because you ignored what pacman told you when you installed dkms and didn't bother reading about it in the wiki.

Re: can't find my ethernet controller device
So there's your NIC and your module and it's also showing up in lshw and likey "ip a" - is there an actual problem or is this more a theoretic exercise?
What's the output of "ip a" and "systemctl status dhcpcd"?

How did you configure it? dhcpcd isn't running or set to run.

Re: can't find my ethernet controller device
Thanks, I think it's solved now with
sudo set ip link enp0s20f0u1 up
sudo dhcpcd enp0s20f0u1I just got confused looking at the Ethernet wiki page when I couldn't find the kernel module as per the example.
