Non-compliant USB Type-C cables with the SLC8000 USB module

There is an article that indicates a non-compliant USB C-Type to Standard-A plug or Micro-B receptacle can damage my PC. Is this possible?


Some non-compliant USB cables with a Type-C connector on one end and a legacy Standard-A plug or Micro-B receptacle on the other end incorrectly terminate the Configuration Channel (CC) with a 10kΩ pull-up to VBUS resistor instead of the specification mandated 56kΩ pull-up resistor. This causes a device connected to the cable to incorrectly determine the amount of power it is permitted to draw from the cable.

USB Cables with a non-compliant resistor may not work properly with certain products, including Apple and Google products, and may even damage power sources such as chargers, hubs, or PC USB ports.

CC is connected to pin A5
Vbus is connected to pins A4, B9, B4 and A9
