Describe the bug

When using the USB-C port on the Prusa xBuddy board with the MMU connected, the firmware reports an MMU Overcurrent error.

How to reproduce

When the printer is off, connect a USB-C cable from the xBuddy Board to a laptop, and ensure there is an MMU connected and the option for MMU is on. Then, turn on the PSU and the error will occur.

Expected behavior

The printer should be able to turn on normally with no problems. To resolve this issue, the MMU was disconnected and the printer no longer gave the error.
