iProg programmer not connected — Troubleshooting Guide

Quick checklist

Power: Confirm the iProg unit is powered (LEDs on).
Cable: Use the original USB cable or a known-good data cable; try a different USB port.
Drivers: Ensure drivers are installed (Windows: check Device Manager for unknown devices or COM port).
Software: Open the iProg software and verify it detects the device. Restart the app.
Firmware: If software shows firmware mismatch, update the iProg firmware per official instructions.
Compatibility: Confirm your OS and iProg model are supported by the software version.
Permissions: On macOS/Linux, run the software with required permissions (or add user to dialout/tty groups on Linux).
Conflicts: Close other apps that may access serial/USB devices (e.g., serial terminals, mobile phone suites, virtualization tools).
Cables/adapters: Avoid USB hubs or unpowered adapters; try a direct connection.
Device-specific pins: If using external adapters or dongles (e.g., OBD, ECU connectors), ensure correct wiring and grounding.

iProg software is often flagged as a "false positive" by security software. These programs may quarantine the ".exe" or communication ".dll" files needed for the link. Disable your antivirus temporarily.
