: Ensure the iProg+ unit is connected only to a 5V USB port on your computer.
Windows 10's driver signature enforcement can block unsigned drivers commonly used by clone devices. To bypass this:
If you have tried all software fixes and the device is still not detected, you may be facing a hardware fault.
Step 4: Disable Driver Signature Enforcement (Windows 10/11) iprog programmer not connected new
If you see a yellow exclamation mark or "Unknown Device," right-click and manually update the driver using the "Drivers" folder provided with your iProg software.
Ensure the port specified in the software matches the COM port number listed in your Device Manager. 4. Adjust Antivirus and Windows Defender Settings

One of the most overlooked causes of the "not connected" error is using the wrong software version for your specific programmer:
The iProg+ hardware requires a highly stable, uninterrupted 5V power supply from your computer's motherboard to initialize its internal processors.
: iProg requires stable 12V for many operations (like EEPROM or MCU programming). Ensure your external power supply is connected if the script you are running requires more than just USB power.
