Furthermore, standard inbox drivers provided by Microsoft do not cover this specific niche hardware. Consequently, when the device enters efe8 mode, Windows 11 recognizes the hardware ID but fails to assign a functional driver, leaving the device in a perpetual "Device cannot start" state (Code 10) or listed under "Other Devices" with a yellow warning triangle.
If official software tools fail, you can use a generic USB driver utility called Zadig to force Windows 11 to recognize the device.
