Solving the Mystery of USB\VID_1F3A&PID_EFE8: The "Allwinner" Driver Guide

If you have landed on this page, you are likely staring at an entry in your Windows Device Manager that looks like a cryptic code: USB\VID_1F3A&PID_EFE8&REV_02.

You probably see a device labeled "Unknown Device" with a yellow exclamation mark, and no matter how many times you click "Update Driver," Windows insists it can't find one.

Don't worry; your computer isn't broken. You have just encountered a very specific piece of hardware common in the hobbyist and electronics world. Here is everything you need to know about identifying and fixing this driver issue.

6. Important Security Warning

Do not download "automatic driver updater" software that claims to find a driver for VID_1F3A&PID_EFE8. These tools almost never solve the problem and often install adware, spyware, or even malware that hijacks USB communication. Stick to Zadig, official CH341 tools, or Microsoft’s own WinUSB.

2) Find an existing driver

The Core Takeaway:

You are not looking at a mouse, keyboard, or webcam. You are looking at a cellular modem (a 4G/5G dongle or embedded module) that Windows does not currently understand.

For Linux Users (udev Rules)

Linux usually detects the device correctly, but you need udev rules to access it without root privileges (required by tools like sunxi-tools).

  1. Create a new rule file: 
    sudo nano /etc/udev/rules.d/99-allwinner.rules
  2. Add the following line to the file: 
    SUBSYSTEM=="usb", ATTRidVendor=="1f3a", ATTRidProduct=="efe8", GROUP="plugdev", MODE="0660"
  3. Reload the rules: 
    sudo udevadm control --reload-rules
sudo udevadm trigger

Final Recommendation

For most users reading this, your device is a generic USB-to-UART adapter. Here’s the fail-safe sequence:

  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).

After a successful install, your device will appear under Ports (COM & LPT) as “USB Serial Port (COMx)”.

Last tested: Windows 11 23H2 & Windows 10 22H2. Works for both 32-bit and 64-bit.

The hardware identifier USB\VID_1F3A&PID_EFE8&REV_02 refers to a specific low-level communication state for devices powered by Allwinner Technology processors. DeviceHunt The Backstory: "FEL Mode"

This driver is not for a typical consumer peripheral like a printer or mouse. Instead, it is the signature of an Allwinner device in "FEL Mode" The Trigger:

A device (such as an Android tablet, TV box, or single-board computer) enters this mode automatically if it cannot find a valid boot image on its internal storage. The Purpose:

It acts as a "recovery" or "flashing" state. Once the device is in FEL mode and connected to a PC via USB, it reveals itself as VID_1F3A&PID_EFE8 The Action:

Technicians and hobbyists use this mode to upload new firmware, unbrick a "dead" device, or run low-level diagnostics using tools like the sunxi-tools Driver Details

If your Windows Device Manager shows an "Unknown Device" with this ID, it usually means your Allwinner-based hardware is waiting for instructions to boot or be flashed. Driver Scape Manufacturer: Allwinner Technology Common Version:

v1.0.0.1 (released circa 2013) is the standard legacy driver used for Windows XP through Windows 10/11. It serves as a bridge for software like PhoenixSuit to communicate with the processor's internal ROM. DeviceHunt When You’ll See It Search the vendor’s website (using vendor/model name found

You will likely encounter this driver in the following scenarios: Unbricking: Trying to fix a tablet that won't turn on past the logo. Development:

Uploading custom Linux kernels to Allwinner-based development boards. Accidents:

If a device's internal storage (NAND/eMMC) is corrupted, it may fall back to this mode, appearing to your computer as this specific USB ID. for an Allwinner device?

FEL mode repeatedly connects and disconnects. Is this normal? 13 Feb 2020 —

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?

FEL is a low-level subroutine in the boot ROM of Allwinner processors (like the A10, A13, or R16). It is used for firmware recovery or initial programming via USB when the device cannot find a valid boot image on its internal storage. Driver Details & Compatibility

The "REV 02 3" (often seen as REV_02B3) refers to a specific revision of the device's firmware or hardware interface. USB Device(VID_1f3a_PID_efe8) Driver for System

Body:

If you have found an unknown device in your Device Manager with the Hardware ID USB\VID_1F3A&PID_EFE8&REV_02, you are likely working with a device based on the Allwinner architecture. Specifically, this ID is almost exclusively associated with Allwinner A-series SoCs (like the A33 or A13) entering FEL Mode.

Here is a breakdown of what this device is and how to get it working.

Method 2: Zadig (For Advanced Users)

If you are planning to use this device with low-level tools like sunxi-fel on Linux subsystems or via command line, you might prefer to use Zadig.

  1. Download Zadig (a free Windows application for installing USB drivers).
  2. Plug in your device.
  3. In Zadig, go to Options > List All Devices.
  4. Find the device corresponding to your Unknown Device (it may show up as "Unknown" or with the Device ID).
  5. Change the driver target to libusb-win32 (or libusb0).
  6. Click Install Driver.

This method is excellent because it allows tools like Python scripts to communicate directly with the hardware without proprietary software bloat.

How to Install the Correct Driver

To get this device recognized, you need a specific driver that handles the Allwinner FEL protocol. The best tool for this is an open-source driver package commonly used by developers.

Quick test: Is it a serial adapter?

Open Device Manager → Action → Add legacy hardware → Install manually → Ports (COM & LPT) → Standard Serial over Bluetooth (just to see if Windows offers a driver). If it accepts but doesn’t work, you need the specific driver below.
