STM32F469I as USB Host communicating with modem

Hi.

 

 

I've got external modem that enumerates 6 virtual com ports and only one of those are available for AT commands. I've looked at the examples and the libraries and I do not quite get how to choose the com port that I might communicate. The CDC_standalone example just establishes the communication with the device, but there's no selection or anything.

 

Is there any examples or documentation how to enumerate the different endpoints?
