FreeRTOS USB Host example

I need a STM32F411 DISCO USB Host example using FreeRTOS.

My project is based on STM32F401. I don't have target hardware yet & have survived with a NUCLEO 401 and linking wire. That won't be good enough for USB.

Nearest is a STM32F411 DISCO but my rushed conversion is not getting past HOST_USER_CONNECTION.

I'd rather not tidy code up and make multi target.

Instead I could develop the USB HOST code unit if only I can find a (working!) FreeRTOS USB HOST STM32F411 DISCO example.
