UsbDk (USB Development Kit) is an open-source driver library that allows Windows applications to have exclusive access to USB devices by detaching them from the standard Windows PNP manager. Version 1.0.22 (x64)

, which frequently fail when they cannot properly capture a device's USB port. Key Takeaways from Reviews
