https://learn.microsoft.com/en-us/windows-hardware/design/component-guidelines/usb4-interdomain-connections https://learn.microsoft.com/en-us/windows-hardware/design/co... > the Ethernet over USB4 interdomain protocol, also known as USB4NET enables two USB4 PCs to establish a network connection between each other when connected using a USB4 cable, akin to connecting an ethernet cable between network cards on two PCs. I wrote about this a month ago at https://news.ycombinator.com/item?id=32714807 https://news.ycombinator.com/item?id=32714807 it gets confusing because the USB4 protocol uses the word "routers" for hosts, devices, hubs which of course is used by Ethernet for something totally else.

Ah I missed it, TYVM! It's great to see that such a feature made it into USB4 now that it's going to reach these speeds. > I do not quite know what happens if you were to plug three hosts together via a USB4 hub. As my post above details, USB4NET properly travels over the hub but which hosts pair, I can't even guess. Can't wait to see people trying this and reporting!

It's rather unfortunate that you still have dig so deep to look up the auto-assigned IPs and then manually type them in Explorer. It really ought to be as simple as file transfers from a PC to a phone - plug the cable, each side gets a prompt on whether it wants to provide access, and once you confirm, the other end shows it in the drive/device tree in Explorer.
