GE Supra DisplayKey USB Cradle (COM4) Driver

The GE Supra DisplayKey USB Cradle needs a dedicated driver to appear as a virtual COM port, usually COM4, on your Windows PC. This driver converts USB communication from the cradle into a standard serial interface that DisplayKey software can use for programming, updates, and data transfers. Once installed, the cradle works reliably with your existing key management tools while keeping simple USB plug-and-play convenience.

Key Features

• Creates a stable virtual COM port for the GE Supra DisplayKey USB Cradle so it can be recognized as COM4 or another available serial port.
• Compatible with Windows 11, Windows 10, Windows 8, and Windows 7 in both 32-bit and 64-bit versions.
• Maintains consistent device identification across different USB ports and system restarts, reducing setup interruptions.
• Supports dependable read and write operations with the DisplayKey, helping prevent synchronization failures and communication timeouts.

How to Install

1. Download the driver package for the GE Supra DisplayKey USB Cradle and extract the files to a folder that is easy to access.
2. Connect the cradle to a free USB port on your computer. If Windows tries to install a generic driver automatically, allow the process to finish before continuing.
3. Open Device Manager and locate the cradle under Other devices or Ports (COM & LPT). Right-click the device and select Update driver.
4. Choose Browse my computer for drivers, select the folder where you extracted the driver files, and click Next. Approve any Windows security prompts that appear.
5. Restart the computer if requested. After restarting, open Device Manager and confirm the device shows as GE Supra DisplayKey USB Cradle (COM4). If a different COM number is assigned, open its Properties, go to Port Settings > Advanced, and change the port number to COM4 manually.

Common Issues and Fixes

• Install fails: Run the GE Supra DisplayKey cradle driver installer as administrator, reboot, then connect the cradle. If blocked, temporarily disable driver signature enforcement only if using a signed/approved GE package.
• Device not detected: Check Device Manager under Ports (COM & LPT). Try a direct USB port and a known-good cable; confirm the cradle appears as COM4 and is not disabled or hidden.
• COM4/version conflicts: Close DisplayKey software using the port, uninstall older GE/Supra USB-serial drivers, reinstall the current package, then reassign the cradle to COM4 in Device Manager.
