USB Host communication

I've got a device with an STM32 micro in USB device mode with a program  of virtual com, that communicates fine with the PC and let me send and receive from the device commands by virtual COM.

Now I want to develop another device which has to communicate with the first device using the USB port (like if the new device was the PC). I'm using a connectivity line micro in these case in order to make it as a host, but I don't know where I could find an example of this type of communication between the devices.

Any one could give an idea for the most similar example for what I'm trying to do?
