Install USB driver (Windows)

A driver package must be installed to use a USB-based product with UHD software:

Download the driver from the UHD wiki page here.
Unzip the file into a known location. We will refer to this as the <directory>.
Open the device manager and plug in the USRP device. You will see an unrecognized USB device in the device manager.
Right click on the unrecognized USB device and select update/install driver software (may vary for your OS).
In the driver installation wizard, select “browse for driver”, browse to the <directory>, and select the .inf file.
Continue through the installation wizard until the driver is installed.
