Composite Devices Support

[arduo]

Hi there,

i wondered if it's possible to support more than two composite device classes. I am using stm32f407ig and in the reference it says there is a control endpoint 0 and it supports 3 IN/OUT Endpoints. So it must be possible to implement CDC+HID+MSC or am i wrong?

Anyone has experience with composite and how to implement it the best way?

​Sure, composite devices can have > 2 functions. The limiting factor is number of available endpoints.

Any idea how to implement that because if I am right i think i need an extra driver for every combination of device? Like if i want 3 Device Endpoint then i need an extra driver
