Usb Vid 1f3a&pid Efe8&rev 02 3 Driver ((link))

The Hardware ID USB\VID_1F3A&PID_EFE8 identifies a device using an Allwinner SoC (System on a Chip) that has entered FEL mode. What is FEL Mode?

  • Install the Prolific driver from Option A.
  • Reboot normally.

    • Step 3: Obtain the Vendor-Specific Driver (If Above Fails)

    If WinUSB does not work, you need the manufacturer’s driver. Since Ours Technology does not publicly list this PID for consumers, try these sources: usb vid 1f3a&pid efe8&rev 02 3 driver

    1. Install CH340 driver (harmless even if wrong chip).
    2. If no luck, install Prolific legacy v3.8.25 with signature enforcement off.
    3. If still dead, download Zadig, click “List All Devices”, select your 1F3A device, and install libusb-win32 (this works for 90% of remaining cases).

    The USB\VID_1F3A&PID_EFE8&REV_02 device is not a virus, nor is it a critical Windows component. It is a specialized piece of hardware that expects a specific driver. By using Zadig to install WinUSB or locating the original programming software from your device’s manufacturer, you can resolve the "driver unavailable" error in less than five minutes.

    The journey led Alex to a somewhat obscure but incredibly useful database that cataloged USB devices by their VIDs and PIDs. After entering the VID 1f3a and PID efe8 into the database, Alex discovered that the device was a specialized USB-to-serial converter, designed for industrial applications. However, the entry also noted that the device required a specific driver to function correctly on most operating systems. Step 3: Obtain the Vendor-Specific Driver (If Above
