Allwinner FEL mode bootloaders often struggle to establish handshakes with modern USB 3.0/3.2 (blue) ports. Plug your data link into an older USB 2.0 (black/grey) port .
Sometimes, REV_02 indicates a known hardware fault. Revision 2 of this chip has a documented bug where it drops its firmware signature after a power surge. If the device gets静电 shocked, the VID/PID remain, but the internal signature fails. In this case, no driver will work . The device is bricked.
: Point to the folder where you extracted the Allwinner driver files. Complete Installation : Click Next to install the driver. Method 2: Manually Installing via Device Manager If you only have an .inf file, use this method. Open Device Manager .
A common approach on developer forums involves the following method:
In technical terms, FEL (which stands for “Firmware Easy Life” or similar) is the boot ROM routine that executes when the SoC cannot find a valid bootable image in NAND flash, SPI flash, or on an SD card. In this state, the chip presents itself to the host as 1f3a:efe8 and waits for commands over USB — allowing you to upload, run, or burn firmware directly from your computer.
: This PID usually appears when the device is stuck in, or put into, FEL mode (fast bootloading mode) or when connecting an Allwinner-based device to a PC for firmware flashing via tools like LiveSuit or PhoenixSuit.
This common issue often occurs when the board is not properly grounded or the power is insufficient.
Upon reboot, press or F7 on the keyboard to select Disable driver signature enforcement . Step 2: Extract the Driver Files
Look for "Unknown Device" or "USB Device(VID_1f3a_PID_efe8)" under Universal Serial Bus controllers Update Driver: Right-click the device → Update driver Browse my computer for drivers Select Folder: Point to the folder where you unzipped the driver files. Driver Scape
Because this driver is typically unassigned and self-contained (lacking an automatic Windows Update package), it must be installed manually. Method 1: The Recommended Manual Deployment
USB VID_1F3A&PID_EFE8&REV_0203 Driver: Complete Installation Guide
This is a legitimate hardware identifier for an Allwinner SoC in a low‑level boot mode. It is not malware. However, if you see this device persistently in Device Manager on a computer that has no Allwinner hardware attached, it may indicate that a piece of Allwinner‑based hardware (e.g., a cheap USB gadget or TV dongle) is connected and in FEL mode unintentionally.
. This is a low-level flashing or recovery mode used for tablets, development boards, and SoCs (System on Chips). DeviceHunt
The generic or libusb-win32 driver must be assigned to this hardware ID.
