I'd like to activate the user USB on the NUCLO.H753ZI board, as a USB device for serial emulation (CDC)
I use CUBE generated code (basic demo setup for this CPU), the ST-Link USB works and I can debug. I may add, that I have USB working with Cube-code on stm32F-series, so the basics should be there.
In CUBE I set the USB to "Device_only". But when I connect the user USB (CN13) nothing happens, the PC does not recognize a new USB.
The documentation (UM2407 User manual) is a little fuzzy there, but I tried to remove the bridge SB77 , which results in LED 8 (VBUS) only be on when user USB is plugged in, but no other success
Questions:
- Do I overlook sth. obvious?
- The USB is basically OTG. Is there something in the connector or elsewhere to be done
- I found example code but not for this particular CPU. Is there an example around for this CPU, where I can peek?
