drivers/usb/usbd: Add Microsoft OS Descriptors #32

Closed jonasblixt closed 8 months ago

jonasblixt commented 8 months ago

When a new USB device enumerates on Windows the system will ask for string descriptor 0xEE, Which is Windows specific, if the string descriptor contains 'MSFT100' it will issue a vendor specific request for a 'Microsoft Compatible ID Feature Descriptor'.

With these two in place Windows will automatically bind the device to WinUSB and in turn we can use libusb directly.

Historically this was handled by the windows binary installer that bundeled libwdi.

It's explained in greater detail here: https://github.com/pbatard/libwdi/wiki/WCID-Devices
