RE: Dell XPS 13 9360 USB ethernet (Dell adapter) not recognised after wake from suspend
hi @mitsos1os. It seems that I have a problem very similar to yours. I would need to get XPS 13 9360 to wake up on a wired Ethernet connected through a USB-C adapter. I am using Ubuntu 17.10.
Were you able to get your system working after all? I'd appreciate any clues.
