libusb Runtime Library
libusb-1.0.dll is an open-source, cross-platform USB communication dynamic link library, used for USB communication between the UHD framework and RF210 devices on Windows. The UHD 4.2 Windows installer does not include this runtime library; its absence causes errors in commands such as `uhd_find_devices` and `uhd_usrp_probe`, preventing RF210 device recognition. This resource is a 64-bit version compiled with VS2019, fully compatible with the build environment of the `uhd_4.2.0.0-release_Winx64_VS2019.exe` installer. It is intended to be deployed into the UHD `bin` directory to resolve USB interface recognition issues.
