They did recently add support for standard serial devices[1]. I'm not sure if this support extends to USB or what any such timeline looks like.

It does seem to work with USB serial devices, but only because those drivers on windows in turn emulate a serial port.

So we have the USB driver pretending to be a serial port to Windows pretending to be a TTY to the Linux subsystem.

It's a bit silly, but then I imagine TTY is a whole lot easier to emulate (even with all the cruft on that) than a USB chipset.

Tangential, but there was a recent HN article (I think) (that for the life of me I cannot find a link to) that referenced a Microsoft DSL for describing finite state machines that was principally developed to implement MS's USB driver. Closest link I could find (which is not the correct one) is: https://www.microsoft.com/en-us/research/project/model-based...

Perhaps it was this one from 13 days ago, about Prolog and Windows NT network configuration? https://news.ycombinator.com/item?id=14046420

No, that wasn't it.
