Running the demonstration project from STM32Cube and tried to load pictures from USB disk. Power does not turn on for USB HS port. Traced the problem to CPEN pin on USB3300. Anybody have a similar board, and does it work?

Ok, problem was caused by my ulinkPro (turned off) being connected to CN13 trace port.
