STM32F4Discovery USB with 2 Virtual Com Port

Hi,

currently i 'm trying to get 2 virtual com ports running via usb cdc implementation. The cdc implementation with 2 interfaces (without iad) uses the virtual com port driver von St and it works fine. Now i try to modify the descriptor with 4 interfaces (2 control and 2 data). For that i insert the iad descriptor for both interfaces. Also i think i have to modify the inf file wit the MI_00 / MI_02 infomation but i don't know how to do this. Does anybody have a working inf file for this? 

Any other solution is very welcome.

Best regards,

Matthias
