There are some examples on how to create composite devices for the Keil USB rom drivers, but none for NXPUSBlib. Suppose I succeed to merge the descriptors so that enumeration sees HID+MSC devices, is this even reliable? Because there is only a single buffer for all endpoints (in and out)? For example when I'm reading from the MSC device and writing to the HID device at the same time, data should not get corrupted. Anyone tested this?
