3.1 Confirm Successful Installation using the Cypress USB Console

Run the Cypress USB Console application and perform a "Get Device Descriptor" operation. The

Console is added to the Windows Start menu by the DVK Setup program under:

Start->Cypress->USB->CyConsole – EZ-USB mode

This link starts the USB Console in EZ-USB mode.

After starting the USB Console, click on the “GetDev” button to retrieve the Device Descriptor from

your Development Board. The USB Console should display the response from the Development

Board shown below. The “idVendor” (VID) value of 0x04B4 is the Cypress Semiconductor vendor

ID, and the “idProduct” (PID) value of 0x0082 identifies EZ-USB the FX2LP Development Board.

The PID will be different if using an FX1 Development Board. The important thing here is that the

board responds to the request and that the VID is 0x04B4. You may wish first to clear the screen

by clicking the “Clear” button. The “GetDev” button may be clicked anytime, as many times as you

wish.

the Console’s features. A link to the Users Guide is added to the Windows Start menu by the DVK

Setup.
