Hi, I was trying to configure Maril properly for my SKR V1.4 but because I once forgot to remove the USB cable from the PC and the board while transferring the jumper from PSU to USB (the PSU was turned off) I now get a malfunction with the computer every time I try to connect it this is PSU and USB I can read the sd card and upload new firmware on it.

Are there more people with this problem?

If you have trinamic drivers it is possible they died when the board was powered by usb and did not have driver power applied.
