USB serial only with D+ and D- pins
I developed a board using the STM32F405RGT6 microcontroller and connected the pins PA_9 (vbus) and PA_10 (otg id) to some peripherals (and it cannot be changed) and only the pins PA_11 (D-) and PA_12 (D+) are connected to the USB. The problem is that now I can't create a virtual serial port over USB using "USBSerial serial();" since the API requires all four pins connected to the USB. Is there any workaround?
