13. B Driver Problems This section discusses the usual problems with the driver installation and how to fix it The most common problem encountered is that Windows did not properly install the driver and so the ICD is not recognized This may also cause the device status to indicate that the device is not working properly An indication of this problem is the ICD status yellow LED it blinks about 2 3 times a second When the driver is installed properly the yellow LED should only blink every second Before trying the following steps try restarting your PC and see if this resolves the problem You can check the status using the Device Manager If the ICD appears under the Universal Serial Bus Controllers with NO red X or yellow exclamation point the driver was installed properly NOTE If you are using Windows 2000 or XP you need Administrator privileges to install the drivers For cases where the Device Status states the device is not working properly please try the following e Double click on Renesas USB Monitor and a Renesas USB Monitor Properties dialog box appears e Click on Driver tab and click on Update Driver button e Select Display a list and click on Have Disk button Specify and locate the C Renesas FoUSB USB Drivers folder on your PC and install usbmon sys driver If you encounter problems on installing the drivers you can try the following 1 Windows 2000 i Copy the fousb inf
