USB driver installation made easy
Zadig is a Windows application that installs generic USB drivers, such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices.
It can be especially useful for cases where:
- you want to access a device using a libusb-based application
- you want to upgrade a generic USB driver
- you want to access a device using WinUSB
Note: "libusb-based" above means an application that uses either libusb, libusb-win32 or libusbK.
