Do USB-C ethernet adapters work with QubesOS?
Good question. I’ve found a related discussion (a bit technical, though):
If you’re planning on using a USB Ethernet adapter, be aware that you’ll need to make sure that
sys-net has access to the USB device.
One way to do that is to select the option Use sys-net qube for both networking and USB devices during the Qubes OS setup, just after installation.
Use sys-net qube for both networking and USB devices: You should select this option if you rely on a USB device for network access, such as a USB modem or a USB Wi-Fi adapter. (source in the docs, with more context)
Besides that, I know for a fact that some work without issues; that may depends on the model. I may be wrong, but I wouldn’t expect the fact that the adapter has an USB-C interface would much difference to any other USB. I’d also expect most Ehternet devices to be well supported. Again, I may be wrong. If anyone knows better, please correct me!

Thank you Gonzalo i appreciate the reply.
I do not rely on USB exclusively for internet but i do require more than one network input to access different networks.
Is anyway i can setup post installation another sys-net vm on QubesOS with USB support?
I think so. I haven’t done this before, but I believe that
sys-usb is a regular VM with a USB controller attached to it. (@ludovic Is that true?) If I’m correct, you could clone your existing
sys-net and assign a USB controller to it.
One way to do that is using the Qube Manager, or via the command line, like described by the 6-step instructions in this forum post.
I let you figure out how your own USB controller is called, and replace
sys-net by the name of your own clone. As far as I can tell, USB controllers have names like
Again, I’m not on my machine, and I’m not able to actually try this, please be careful and use your judgment, or wait for someone else to confirm!
Additional warning of you start experimenting with where you attach your USB controller, and rely on a USB keyboard or mouse:
My understanding is that attaching your controller to one VM would detach it from the other VM. If your keyboard or mouse were attached to it, they would get disconnected.

I don’t see any problem for doing this.
@Pixel : yes you could do this later, with post-installation, but on installation add the optional sys-usb it’s a simpler way. So first do a basic installation, read the documentation, understand all this works, play with Qubes OS and later go to this advanced setting.
