Hi everyone, I have 32F429IDISCOVERY and I want to make some ''CAN to USB converter'', but when i choose CAN1 or CAN2 and USB device with Virtual COM port, device not identified in windows 10 with error 43 (A request for the USB device descriptor failed.). If I disable CAN, USB work fine.

I found reason. Cube MX by default choose CAN1Tx and Rx on PA11 and PA10. If change to PD0 and PD1 its start working well.
