Once you are confident the hardware is stable, you must ensure that your Windows operating system isn't putting the device to sleep when it detects a spike in temperature or power usage. 1. Disable USB Selective Suspend

If you are getting 10V or 12V errors, you may need to replace resistors on the mainboard. Specifically, look to replace: One 4.7k Ohm resistor. One 51k Ohm resistor.

By systematically isolating the main unit from the adapters and verifying your electrical connections, you can safely pinpoint whether your "iProg not connected hot" issue is a simple chip placement error or a hardware failure requiring component repair. To help troubleshoot your specific issue, let me know:

Right-click the Windows Start button and select . Expand the Universal Serial Bus controllers section.

The fault is in one of your adapters or the ECU/vehicle connection. If it still gets hot: The fault is inside the iProg unit. 4. Check for Driver/Software Issues Ensure the iProg software is installed correctly.

Open Device Manager in Windows and ensure "iProg universal programmer" appears under "Network adapters" or "Other devices" without a yellow exclamation mark.
