| Problem | Solution | |---------|----------| | | 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 |
| Problem | Solution | |---------|----------| | Driver shows “Not digitally signed” | Disable driver signature enforcement (method above). | | Code 10 (device cannot start) | Uninstall device → Scan for hardware changes → Reinstall driver manually via “Update driver” → Browse → Let me pick → Have disk → Point to CH341 driver .inf . | | Programmer detected but software (Ezp2010 GUI) says “No device” | Ensure (e.g., Arduino IDE, Putty) uses the same COM port. Change COM port number in Device Manager (Ports → Advanced → COM number e.g., COM2). | | CH341 driver overwritten by Windows Update | Roll back driver via Device Manager, or use Group Policy → Computer Config → Admin Templates → System → Device Installation → Prevent installation of devices not described by policy. | | 32-bit vs 64-bit mismatch | The official CH341 SETUP.EXE detects OS architecture automatically. If not, manually install .inf via Have Disk . | Ezp2010 Programmer Driver Windows 10
✅ Once the driver is installed correctly, your EZP2010 will work reliably on Windows 10 for SPI flash programming. | Problem | Solution | |---------|----------| | |
