Usb Vid 1f3a&pid Efe8&rev 02 3 Driver -
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.
Encountering an unknown device in Device Manager with the hardware ID USB\VID_1F3A&PID_EFE8&REV_02.3 is rarely a sign of broken hardware. More often, it is a cry for software help. This guide will decode exactly what this device is, why Windows doesn't recognize it, and how to safely install the correct driver.
If you want a specific artifact (email, udev rule, Windows INF steps, or libusb sample), tell me which and which OS you’re using; otherwise I can assume Linux and provide an example.
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 usb vid 1f3a&pid efe8&rev 02 3 driver
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
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 —
