USB driver installation only needs to be done once on a Windows PC, normally before connecting a device to the PC for the first time.
Download the USB installer from the Lectrosonics website: https://lectrosonics.com/Support/category/66-usb-drivers.html
Two versions of the USB driver installer are provided, for different types of Windows PC:
Double-click to launch the desired installer.
The WD USB Device Installer opens.
Click Next to proceed.
The EULA is presented.
Accept, then click Next to proceed with installation.
When installation is complete, the Driver Name and Status are displayed. Click Finish to close the Installer. You may now connect any DR Receiver frame to the PC and drivers will be loaded automatically.
