Click Start | Programs | Flash Wizard to launch the Flash Wizard. The Identifying Devices dialog box is
displayed as Flash Wizard locates and identifies the devices connected to your system.

and that all cables are correctly and securely attached. Verify that the terminal application or
software application is turned off.
