Thanks for the reply! The USB resistor is 1.5K. Some HID joystick code I tested works fine on the board when uploaded using ST-Link, the bootloader by Roger Clark (stm32duino)...

Thanks for the help, I just tried it but alas, the problem remains.

I'm having the same problem, is there a solution to this?
