Require:
I use the library(STM32_USB-Host-Device_Lib_V2.1.0). I run the example ''USB_Device_Examples\VCP'' I find STM32F4xx as USB Device in the example. But in my design, STM32F4xx will be as USB Host on VCP. Because I require many com ports.
Questions:
1. STM32F4xx as USB Host, other chips as USB device, communication by Virtual Com Port. Current USB Library can do it ? 2. If first can do, How many virtual com ports will be virtualized? 3. If first and second can do, What to do? Please.
