Symptoms

  • Kills USB-C devices

Solution

Make sure that 20 V is only present on C3101 OR C3201 (PP20V_USBC_XA_VBUS OR PP20V_USBC_XB_VBUS). If A is making 20 V on B, or vice versa, likely need to replace the MOSFETs Q3100 and/or Q3200, since they're letting 20 V through (backwards!) when they're not supposed to.
