Example for PICO_STDIO_USB_ENABLE_RESET_VIA_VENDOR_INTERFACE

[JohnAZoidberg]

I can't figure out how to use the sdk to enable the vendor reset interface.
Also PICO_STDIO_USB_RESET_INTERFACE_SUPPORT_MS_OS_20_DESCRIPTOR.
I tried to replicate this interface manually without the SDK but cannot get windows to recognize it properly
I would appreciate a working example with:

PICO_STDIO_USB_ENABLE_RESET_VIA_VENDOR_INTERFACE=1
PICO_STDIO_USB_RESET_INTERFACE_SUPPORT_MS_OS_20_DESCRIPTOR=1

Thanks!

I figured it out, most of the usb examples cannot add this, or it won't do anything, because they have the device and configuration descriptors manually defined. So this config won't be able to add the necessary interface.
Only in the hello_world example it does anything useful.
That helped me a lot.
