This device is an Allwinner-based gadget—likely a cheap Android tablet, an Orange Pi/Raspberry Pi clone, or an ebook reader—that is currently plugged into your computer in "Flashing Mode." This mode is used to flash custom firmware (like Android or Linux) onto the device.
Hold down the Shift key while clicking in the Windows Start Menu.
The identifier refers to an Allwinner Technology device in FEL mode . This is a low-level "flashing" or recovery state used to provision or repair devices (like tablets or development boards) using an OTG connector. Device Profile Vendor ID (VID): 1F3A — Allwinner Technology.
This is the standard way to install a generic USB driver for FEL mode. Download and run Zadig . Go to > List All Devices . Select USB Device(VID_1f3a_PID_efe8) from the dropdown. Choose WinUSB as the driver. Click Replace Driver or Install Driver . Method 2: Manufacturer Tools
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 usb vid 1f3a&pid efe8&rev 02 3 driver
To resolve the "Unknown Device" error or proceed with flashing, you typically need the Allwinner USB Driver Manual Update via Device Manager: Device Manager by right-clicking the Start button and selecting it.
: If the driver fails to start, try a different USB port (preferably a rear 2.0 port rather than a 3.0 hub).
Because Foxlink produces these chips for custom contracts, they often do push generic drivers to Windows Update. The driver is unique to the final product's manufacturer.
Standard Windows updates rarely include these specialized drivers. Depending on your goal, use one of the following methods: 1. Using Zadig (Best for Advanced Users) This device is an Allwinner-based gadget—likely a cheap
The hardware ID corresponds to an Allwinner Technology SoC (System-on-Chip) device in flashing or recovery mode . When a computer lists this exact string under the Windows Device Manager details tab, it indicates that a connected device—such as an Android tablet, e-reader, smart TV box, or single-board computer powered by an Allwinner processor—has entered its low-level sunxi SoC OTG FEL mode .
Includes the required drivers in its installation directory (usually C:\Program Files\AllWinnertech\PhoenixSuit\Drivers An older alternative for legacy Allwinner-based tablets. Allwinner USB Drivers:
: This is the most reliable way to install a generic WinUSB driver for FEL mode.
This hardware ID ( VID 1F3A & PID EFE8 ) identifies a device in . This is a low-level recovery state used by Allwinner-based devices (like Onda tablets, Orange Pi, or Android TV boxes) for flashing firmware or unbricking. 🛠️ How to Install the Driver This is a low-level "flashing" or recovery state
| Symptom | Likely Cause | Solutions to Try | | :--- | :--- | :--- | | | Incorrect or corrupted driver installed; or the driver failed to load. | Uninstall the device (check "Delete driver software"), then reinstall using the correct method (Zadig/WinUSB). Restart PC. | | "Device cannot start" (Code 10) | Driver conflict; outdated driver; issue with the device's firmware state. | Try a different USB port/cable. Force the device back into FEL mode. Use the specific AW_Driver with PhoenixSuit. | | Driver installation fails (Error code) | Corrupted driver file; antivirus software blocking the install; Windows security feature interference. | Temporarily disable antivirus. Run installer as Administrator. Use a different driver (e.g., WinUSB). | | Device not detected at all | Physical connection (cable/port); device not actually in FEL mode; power issue with the device. | Test with a known good cable/port. Ensure device is fully powered off before entering FEL. Power some devices via a powered hub. | | Connection is unstable (Windows) | Power-saving settings for USB ports; interference from other USB devices. | Disable USB selective suspend in Power Options. Try the device on a different PC to isolate the issue. | | Connection errors in Linux ( sunxi-fel ) | Linux kernel auto-suspend is interfering with the FEL protocol. | Create the udev rule mentioned earlier to disable USB auto-suspend for this specific device. |
: The device is in a low-level boot state used by tools like PhoenixSuit or LiveSuit to write new Android or Linux images.
The VID 1f3a and PID efe8 were unique identifiers assigned to this device by its manufacturer, distinguishing it from the myriad of other USB devices available in the market. The revision number, 02, indicated that this was an updated version, suggesting improvements or fixes over its predecessor.
