USB forwarding to WSL is built in to the WSL kernel, but you do need to install a thing on the windows side. After that, there are a number of GUIs to manage your usb devices or you can use the shell. Switching a usb devices from windows to WSL basically unplugs it from windows and plugs it into WSL.

I need it to access ssh keys from my yubikey. It’s painless if you just set it up to automatically forward the device on startup.
