Troubleshooting Driver Installation

If the installed drivers do not automatically bind to the target device, try these steps:

  1. Open the Windows Device Manager
  2. Identify the target device for driver binding (e.g., Ti60F225 Development Kit (Interface 1)).
  3. Double-click the device name to open the Properties window.
  4. Click the Driver tab.
  5. Click Update Driver.
  6. Choose Browse my computer for drivers and Let me pick from a list of available drivers on my computer.
  7. Select the newly installed driver, e.g., Efinix libusbK USB Device (FT4232H).
    Note: Depending on the target development kit, a different FTDI device may display. See the "Supported FTDI Devices" section below for a full list of devices.
  8. Click Next to update drivers for the device.
  9. Click Close once prompted that drivers have been successfully updated.

If you are cannot identify which device or interface is listed in the Device Manager:

  1. Open the Device Manager.
  2. Double-click the device to open the device properties.
  3. Click the Details tab.
  4. Choose Hardware Ids in the Property dropdown menu.
  5. Identify the FTDI device and interface number using the following schemes based on the Value:
    • See the following table for a list of supported devices and their respective VIDs and PIDs.
    • For multi-interface devices:
      • Interface 0: ends in MI_00
      • Interface 1: ends in MI_01
    • Example Hardware Ids entry for FT4232H (Interface 1): USB\VID_0403&PID_6011&MI_01
