I initially bought this for the Mac, as it is indeed supported. I know Linux is not a supported platform, but at least until kernel with 5.0.5 (and some a bit older and newer), it worked like a charm for my XPS 13 with Linux!
This is when I wrote that small udev rule as a helper: https://gist.github.com/madchap/03aff8f3ceef5c01bc12a4c5fc13f8a8
However, eventually since 5.1 (or a bit less, I didn’t take note unfortunately), it seems to be no longer detected. I had some pciport kernel errors at first, and today with the newer kernels, no messages.
While it still work well with the Mac, I will try to get a new thunderbolt cable to see if maybe it could be a cable issue.
Any ideas or thoughts around the community?
