Solved: OTOFIX D1 “USB Port Not Support Charging Function” Error

If your OTOFIX D1 Diagnostic Tablet displays the error: “The USB port does not support the charging function, please replace the USB port if you need to charge!”, it is rarely a hardware fault. This message usually means the charging cable is plugged into a data port instead of the dedicated power port.

Quick Fix Steps

Follow these steps to resolve the charging error immediately:

  • Unplug the Cable: Remove the USB cable from the current port.
  • Locate Charging Port: Check the device diagram to identify the specific charging-compatible port.
  • Reconnect: Securely plug the cable into the correct designated port.
  • Verify: The error message will clear once the correct port is used.

Why This Happens

The OTOFIX D1 distinguishes between data transfer and power input. Using a data-only USB port triggers this protective alert to ensure the device receives the appropriate voltage.
