WSL2 USB/IP Kernel Build

At the time of writing WSL 2 does not have official support for interfacing with USB type devices. To solve this, a fork of the usbip project is modified by Microsoft to allow virtual connectivity between USB devices on a host via the USB/IP protocol.

Though it is recommended to use the usbip from a Windows 11 host, there is a way to build a custom WSL2 Kernel in Windows 10 with usbip driver support enabled for USB Mass Storage devices.

This is a supplementary guide which allows for a more linear step by step instruction to eliminate the confusion introduced by the official documentation.
