The EZP2010 high-speed USB programmer is a lifesaver for flashing SPI flash and EEPROM chips. However, getting the driver to behave on Windows 10 is notoriously difficult.
Below is a breakdown of why this happens and how to force the driver to work on modern Windows systems. 🛑 The Core Problem: Unsigned Drivers
The default drivers bundled with the EZP2010 were written long before Windows 10 implemented strict security policies.
Driver Signature Enforcement: Windows 10 blocks drivers that do not have a registered digital signature.
Abandonware: The original manufacturer has largely disappeared or moved on, leaving users without updated, officially signed files.
Hardware Conflicts: The device relies on a Silicon Labs C8051F340 MCU. Standard drivers often fail to detect the specific hardware ID (USB/VID_10C4&PID_F5A0) without manual intervention.

To use your EZP2010 on a 64-bit Windows 10 machine, you have to temporarily strip away Microsoft's security guardrails to bypass the digital signature wall. Step 1: Temporarily Disable Driver Signature Enforcement
You cannot skip this step! Windows will silently fail to load the files if you do.
Hold down the Shift key while clicking Restart in your Windows Start Menu.
Your PC will reboot into a blue screen options menu. Navigate to:Troubleshoot > Advanced options > Startup Settings. Click Restart.
Upon reboot, a list of settings will appear. Press 7 or F7 on your keyboard to select "Disable driver signature enforcement."
Your PC will boot into Windows normally, but security checks are temporarily paused for this session. Step 2: Manually Map the Driver The EZP2010 high-speed USB programmer is a lifesaver
Do not rely on double-clicking an automated .exe file; forced manual installation yields the best results. Plug your EZP2010 programmer into a USB port.
Open Device Manager (Right-click the Start button and select it).
Find the device. It will likely have a yellow warning triangle next to it or be labeled as an unknown device. Right-click the device and select Update driver. Choose "Browse my computer for drivers."
Select "Let me pick from a list of available drivers on my computer."
Click Have Disk... and browse to the folder containing your downloaded EZP2010 driver files (specifically looking for the .inf file).
Windows will warn you that the driver is unsigned. Click "Install this driver software anyway." 💡 Quick Tips for Success Device Manager shows “USB Serial Port (COMx)” without
Use USB 2.0 Ports: This programmer was designed in 2010. Plugging it into a modern USB 3.0 or 3.1 port (blue or red ports) frequently causes connection drops. Find a black USB 2.0 port if possible.
Rebooting Re-enables Security: Once you reboot your computer after finishing Step 2, Windows will turn driver enforcement back on. The driver you just installed will remain functional, but if you ever need to reinstall it, you will have to repeat Step 1.
Alternative Tools: If you find yourself frequently fighting the EZP2010 software, consider upgrading to a CH341A programmer. It is equally cheap but has massive open-source community support (like NeoProgrammer and Asurada) that handles Windows 10 natively without jumping through these hoops.
If you need a hand with the specific software version or need a recommendation on where to find clean driver archives without hitting malware walls, let me know! I can help you safely track down the files you need to get your BIOS flashed.
After successful driver installation:
| Problem | Solution | |---------|----------| | “Driver not signed” error | Disable driver signature enforcement (Step 2) | | Programmer not detected | Try a different USB cable or port (USB 2.0 preferred) | | Read/write fails | Reinstall driver, then reboot PC | | COM port not showing | Uninstall driver via Device Manager, reinstall fresh | | Software crashes on open | Run programming software as Administrator |
CH341SER.EXE as Administrator (right-click → Run as administrator)Some modified EZP2010 units can work with generic WinUSB drivers.
