Installation of basic and generic USB drivers

Zadig is a free and open-source device driver installation utility developed by the French software developer libwdi. It is designed to install device drivers for USB devices on Windows in cases where the operating system does not automatically recognize the device or install the appropriate driver.

Zadig allows you to install device drivers in the form of kernel-mode drivers and user-mode drivers, and includes support for various driver installation options, such as installing or replacing existing drivers, and creating and installing system-wide drivers.

Zadig is often used to install device drivers for USB-based hardware, such as USB-to-serial adapters and USB-based peripherals.

Zadig does exactly what you tell it to do. If you select the wrong device, and Zadig happen to replace its driver, the responsibility is entirely yours. Zadig will try to warn about common system drivers, such as HID or Mass Storage, that you don't usually want to replace, but there are only so many drivers Zadig can know about.

Therefore caution should be used when installing these drivers.
