Hi all

I've a little problem. I use the USB driver from st to communicate with my STM32F4-Discovery. This works realy good. But I've would make a streaming protocol with a camera sensor. For this I have to use the MCO1. The parts works but in combination it won't do anything. So I searched for a reason. Then I've found something special in the driver library:
The SOF overwrites the MCO1 configuration from PA8, but this pin isn't used for anything. If I remove the PA8 configuration for SOF output, the usb doesn't work correctly.

So for what is this pin used? Is ist also used internal for something?
Best regards
