connect an external 12V power supply to the main iProg+ unit. This can permanently burn out the internal circuits.
(blue ports). Try connecting to a standard USB 2.0 port or using a USB hub. Check the USB Cable
The bundled USB cables can sometimes be cheaply made and suffer from internal wire breaks. Swap it with a high-quality, shielded USB cable (like a standard printer cable). 6. Run the Software as Administrator
: Faulty or low-quality USB cables can cause intermittent connection errors. Test with a known working high-quality cable to see if the status changes. Serial Number Mismatch
: Faulty USB cables are a common cause of "Not Connected" errors; try a known working cable. Step-by-Step Driver Installation iprog programmer not connected new
The programmer is working and the driver is correctly recognized. REVELTRONICS - Forum Common Fixes for New Setups Reinstall USB Drivers
If software updates and driver reinstalls do not fix the "not connected" status, the issue may stem from component variations on clone circuit boards.
Legacy iProg software (version 1.x or 2.x) often only scans . If your device is on COM7, the software will show "Not Connected."
Look for a yellow warning triangle next to a label like USB Serial Port or iProg+ . connect an external 12V power supply to the main iProg+ unit
Some scripts and adapters (like RFID or BDM adapters) require stable external power. If your new kit came with a power supply, ensure it is plugged in when testing.
Ensure you have the correct software for your hardware:
The iPROG+ should only be connected to the computer's USB 5V port and should not be connected to an external 12V power supply, as this can burn out the device
Some versions of the software require the device to be assigned between COM1 and COM4 . You can change this in Device Manager -> Properties of the device -> Port Settings -> Advanced . ⚠️ Step 4: Hardware Faults (Clones Only) Try connecting to a standard USB 2
: This is the most common cause. If the red LED on the device is blinking, it indicates the hardware is receiving power but cannot communicate with the PC.
If you see an error saying "power loaded," this may indicate a damaged power transistor inside the unit, a common issue with newly received, improperly handled units. 6. Summary of Troubleshooting Steps Probable Cause No Lights, No Detection Faulty cable/port Change USB cable/port Yellow Alert in Device Manager Missing/Incorrect Driver Reinstall FTDI drivers "Not Connected" on Win10/11 Driver Signing Block Disable Driver Signature Enforcement Software Freezes/Errors Version Mismatch Use V87 software instead of V89
Never connect an external 12V power supply to the iProg+ unit itself; it is designed to run on 5V USB power. Connecting 12V can permanently burn the internal circuits.
One of the most overlooked causes of the "not connected" error is using the wrong software version for your specific programmer:
