Where is winusb descriptor string defined?

[karelbilek]

I see in winusb.h:

/* Arbitrary, but must be equivalent to the last character in
   the special OS descriptor string */
#define WINUSB_MS_VENDOR_CODE 0x21

But I cannot see where is the OS descriptor string defined; I sed it only being used in winusb.h

    if (req->bRequest != WINUSB_MS_VENDOR_CODE) {
        return USBD_REQ_NEXT_CALLBACK;
    }

but I don't see the actual descriptor anywhere.

Oh, that's because 0x21 is actually ! and I see it in MSFT101!. I did not notice that. Closing.
