We have released support for accessing the GPU inside of WSL 2 distributions! This means you can now use WSL for machine learning, artificial intelligence, and data science scenarios more easily when big data sets are involved. Check out the get started with GPU support tutorial. As of right now WSL 2 does not include serial support, or USB device support. We are investigating the best way to add these features. However, USB support is now available through the USBIPD-WIN project. See Connect USB devices for steps to set up USB device support.
