Since the STM32F407 has 2 USB ports, OTG_FS and OTG_HS, can both ports run at the same time? I want OTG_FS to operate as a host and OTG_HS to operate as a device at the same time.

All of the sample code from ST operates with either the FS core or the HS core, but not both at the same time.

HI,

We are also going to this and to my understanding there should not be a problem as FS and HS cores have a separated register sets and separate PHY's

I suspect it should be fine, I have seen boards with both, but it presupposes a level of USB and code implementation experience/expertise beyond the scope of the simple examples.
