A test point driver allows your computer to communicate with a Huawei device that has its hardware test points shorted. Huawei devices primarily use HiSilicon Kirin processors. When you short the correct test point to the ground on the motherboard and plug in the USB cable, the device bypasses the standard bootloader and boots into mode. Without the specific test point driver installed, Windows will display the device as an "Unknown Device" with a yellow exclamation mark, preventing service software from interacting with it. 2.
