I'm trying to create a USB CDC+MSC composite device using STM32F4 so that it gets automatically recognized by both STM32 CDC driver and as a standard MSC device. Does ST provide a VID/PID pair for such a device? I mean, ST uses 0483/5740 for CDC examples and 0483/5720 for MSC examples. So, what should I set for a composite CDC+MSC device? Thank you.
