If for some reason the firmware updating process in interrupted (e.g., the USB cable is accidentally removed, or you have a power failure), the EZbus will not have the complete set of operating system instructions it needs to function properly. The most obvious symptom of this condition is the blank LCD.

1) If you are using the latest EZbus driver, you simply need to double-click on the firmware updater to reload the firmware into the EZbus. Note that you may have to do this several times, power-cycling the EZbus in-between each attempt, before the firmware will be successfully loaded. This is normal, and is not an indication of any additional problem.

2) If you are not using the latest EZbus driver, download the zipped file (below) for your operating system (Win XP or ME) to your computer's desktop, or a folder of your choosing

WinXP Firmware zip:
WinME Firmware zip:

3) Unzip the file, again to either your desktop or a folder of your choosing.

4) Navigate to your computer's Device Manager and highlight USB Device. Now go to Properties and click on Update Driver. Point the Update Wizard to the desktop or to the folder into which you downloaded and unzipped the files. At this point, Windows will reinstall the file EZbus.inf, which will allow you to refresh the firmware, as in Step 1, above.

5) Once the EZbus.inf file has been installed, the listing within Device Manager will now read EZbus-Needs Firmware Refresh, rather than USB Device. At this point, follow the procedures outline in Step 1, above, until the EZbus operating system is restored.
