I need some help for my project (I'm using STM32f4 discover board). I would like to exchange data from mcu to pc and pc to mcu. Data will be an array with some informations. I tried USB CDC (works fine) but the throughput is too small. 

I checked examples in STM32_USB-Host-Device_Lib_V2.1.0 and I steel don't understand how I can do.

I have to use host and device example, isn't it ? How can I check if I send data to a pc ? (usb sniffer is it a good choice ?).

If you can provide me an example with code on mcu and program on pc, it will be nice :)

Thanks for any help
