Pixel 3 with Sub Rosa worked right out of the box. If you're trying to get this to work on Linux, you may need to update some libraries and install a driver. I had to get the latest pcsc-lite, pcsc-tools and CCID packages and build them from source. But it works! in summary. From the pcsc-lite package maintainer's blog, this reader is recognized in CCID version 1.4.31.
