Since this is a specialized recovery mode, Windows often doesn't have a built-in driver for it. You can manually install one using these methods: Download the Zadig tool . Open Zadig and go to Options > List All Devices . Select the device labeled VID=1F3A PID=EFE8 .

No. The identifier USB\VID_1F3A&PID_EFE8 is a legitimate hardware signature for an Allwinner chip. While malware could theoretically spoof a VID/PID, encountering this specific string almost always points to a genuine hardware device, not an infection.

: In the driver selection box (right side of the green arrow), select WinUSB or libusb-win32 .

Windows 11 does not include a native driver for this specific hardware ID, which often results in it appearing as an "Unknown Device" or showing a error (Device cannot start) in Device Manager.

Windows 11 has aggressive power management for USB devices. This can cause legacy chips like the FocalTech one to enter a low-power state and never wake up.

There is no "consumer" driver for daily use in this mode. It requires specialized tools like Allwinner PhoenixSuit , LiveSuit , or the Zadig tool to interface with the device.
