Device: iProg programmer Issue: Shows "Not connected" / fails to connect to target or PC. Impact: Prevents programming, diagnostics, or immobilizer operations; workflow halted.
Most iProg programmers use an FTDI chip for USB-to-serial communication.
If you are comfortable with a soldering iron, you can permanently fix thermal disconnects by updating three critical areas on the circuit board:
A surprisingly simple but often overlooked cause: USB 3.0 ports and certain USB hubs can cause communication failures. One user discovered after extensive troubleshooting: "If you have new computer with usb 3 it can cause problems too.
