Get WebUSB Work

The repository contains some utils and notes for WinUSB and WebUSB. On Windows, WebUSB depends on WinUSB. There are 2 ways to get a driver-less WinUSB:

1. use MS OS 1.0 descriptors
2. use MS OS 2.0 descriptors

You can read these descriptors using webusb.py

Notes

• WebUSB doesn't work on a USB composite device using MS OS 1.0 descriptors yet (tested on Windows 10 at 2020-02-14)
• To use WinUSB with MS OS 2.0 descriptors, bcdUSB must be >= 0201
• You can also use Zadig to install a WinUSB driver for a USB device if you can not add these descriptors.
