These instructions describe how to install the ADI ADRF6655 rev 1.1.0 USB factory software GUI, as well as the Cypress Generic USB driver, onto a Windows XP, Vista, or Windows 7 PC running 32 or 64 bit bit OS. 

1. If it is plugged in, unplug the RFG USB adapter from the PC.

2. Extract the ADI ADRF6655_factory_software_1p1p0.zip file

3. This instruction is only necessary if the PC is running Windows 7 OS. Note that there is no harm doing this if the PC is running XP, Vista or Windows 7 32 bit OS. In the extracted subdirectory 'ADI_Windows7_RFG_Drivers', run the ADI_RFG_Drivers.exe file. Running this file will allow the installation of the Cypress CyUSB.sys driver as a verified, signed driver.

4. Now run the file ADRF6655_factory_1p0p0_installer.exe from the extracted .zip file. An icon should appear on your desktop with the ADI logo, entitled ADRF6655.

3. Once the installer is finished, you will need to install the USB driver. Plug the RFG USB adapter into the PC using a USB cable. In either XP or Vista, right click on My Computer and then select Properties. In Vista or Windows 7, you then select the Device Manager option. In XP, you select the hardware tab and then Device Manager. In Device Manager, select the last category, Universal Serial Bus Controllers. There will be an entry that either has a yellow flag on it (for unknown device) or it will say ADF4xxx USB Driver (if you have installed the previous ADRF6x0x or ADI Limerick PLL software). Right click on this device and select 'update driver'. Browse to select the directory 'C:\Program Files\ADRF6655_factory_1p0p0'. Click on 'Next' and Windows should complete the driver installation successfully.
