If you’ve recently upgraded to Windows 11 or bought a new PC, you might have discovered that your trusty Ez100pu smart card reader no longer works out of the box. This is a common issue because Windows 11 has stricter driver signature requirements and often disables legacy drivers for security reasons. Title: How to Download and Install the Ez100pu

Don’t worry. In this guide, I’ll walk you through exactly how to get the Ez100pu driver working on Windows 11, whether you need it for digital signatures, online banking, or government ID cards.

What Exactly is the Ez100pu Driver?

Before diving into the technical steps, let’s clarify what this driver does.

• Device Type: The Ez100pu driver is specifically designed for smart card readers using the FTDI (Future Technology Devices International) chipset or proprietary USB controllers.
• Common Hardware: Often paired with devices like the MagicBird EZ100PU, EZ301PU, or similar “EZ-Link” readers. These are widely used in healthcare systems, digital ID verification, and financial sectors.
• Function: The driver acts as a translator between the smart card’s chip and Windows 11’s PC/SC (Personal Computer/Smart Card) framework. Without it, your smart card is just a useless piece of plastic.

The Windows 11 Challenge: Windows 11 has stricter driver signing requirements and has deprecated many older kernel-mode drivers. Older versions of the Ez100pu driver (especially pre-2015 versions) will be blocked outright by Windows 11’s security features. This is why a simple “plug and play” usually fails.

4. Troubleshooting

• Device shows Unknown device / Code 39 / Code 28:
  • Reinstall driver as Administrator; ensure correct INF for x64.
  • Check driver signature: if blocked, temporarily disable Secure Boot or enable test-signing only if you accept security risk.
• Printer prints garbage or fails to respond:
  • Confirm printer works directly on a native parallel port or another adapter.
  • Try different USB port (prefer USB-A 2.0 vs 3.0), use a short cable, avoid hubs.
  • In Printer Properties → Ports, ensure correct port mapping (USB virtual LPT or listed COM).
• Bi-directional features (status, ink levels) missing:
  • Many adapters provide only unidirectional signalling; full bidirectional support may be impossible without a chipset-specific driver.
• Windows update overwrites working driver:
  • Roll back driver in Device Manager and block updates for that device via Group Policy or Microsoft Show/Hide Updates tool.
• 64-bit signed driver not available:
  • If forced to use unsigned driver, disable Secure Boot in UEFI (not recommended for security), or obtain a signed driver.

Step 2: Locate the Official Driver Source

Because the EZ series is manufactured by several OEMs, the best source is often the manufacturer of your specific device. However, the most universally compatible version comes from the original chip designer or national infrastructure providers.

Primary Sources:

1. FTDI Chip Website: If your device uses an FTDI USB-to-serial converter, download the latest CDM v2.12.28 WHQL Certified driver. This often works as a generic replacement.
2. Your Country’s Government PKI Website: In South Korea, the Ez100pu driver is bundled with “AnySign4PC” or “TouchSign.” In Brazil, it’s part of the “Gov.Br” certificate modules. Download directly from .gov.br or .go.kr domains.
3. The Manufacturer’s Archive: Companies like RAON or Kisan Electronics provide legacy driver packs.

Warning: Do not download drivers from third-party "driver updater" websites. These are often malware or outdated bundles. Always use official sources.

6. Recommendations

• If you need reliable, bidirectional printing on Windows 11, use either:
  • An adapter explicitly advertised with Windows 11 (signed driver) and vendor support, or
  • A printer with native USB or network capability.
• Always download drivers from the adapter manufacturer or the seller’s support page.
• Keep Secure Boot enabled; only use signed drivers. Disable only as last resort and re-enable afterward.

Step 3: Install the Driver

1. Extract the downloaded driver folder.
2. Connect the Ez100pu via USB.
3. Open Device Manager → find the yellow-banged device (Unknown or “Ez100pu”).
4. Right-click → Update driver → Browse my computer → point to the extracted folder.
5. Click Next – ignore any “unsigned driver” warnings.
