EZ-USB Development Kit Manual - Getting Started

Page -4 EZ-USB Development Kit Manual - Getting Started Rev 1.0

• Windows 98 and 98SE – For PCI add-in adapters, drivers may be available from the

adapter's manufacturer. However, these versions of Windows are not supported by the

EZ-USB DVK.

You can verify that high-speed drivers are installed and correctly bound to your host controller by

looking under Device Manager. To open the device manager, run devmgmt.msc which is located in

the Windows System32 Directory. After starting Device Manager, scroll down and expand the

“Universal Serial Bus Host Controllers” section. If you see a device entry containing the string

“Enhanced Host Controller”, then your system is configured correctly. If you cannot locate this

entry, then it is likely that the host controller is not correctly bound to the high-speed driver. Look in

the “Other Devices” section of the Device Manager for a USB Device marked with a yellow ques-

tion mark. Right click on this entry and choose “Update Driver”. Then choose the option that allows

Windows to locate the driver for you. If you have installed the required Service Pack, Windows will

bind the controller to the appropriate device driver. You should now see the “Enhanced Host Con-

troller” entry under “Universal Serial Bus Host Controllers”. For further help, contact your PC man-

ufacturer.

2.5 Installing the Development Kit Software

Insert the installation CD into your CD ROM drive and run the program "setup.exe" by going to the

start menu and running Setup.exe on the CD root directory.

For first time users, Cypress recommends accepting the default option at each stage of the Setup.

Even though the Setup will allow you to change the destination folder for the installation, it is

strongly recommended that you accept the default installation directory (c:\cypress\usb) as firm-

ware examples and applications may be path dependent. Also, if you have already installed the

full retail version of the Keil 8051 Development Tools on your system you should choose the “Do

not install” option for the Keil tools.

3.0 Installing the Hardware

The hardware installation procedure is simple and goes as follows:

• Connect the EZ-USB Development board to a USB port on your development PC using

the USB cable.

• When the OS finds the new USB device, it will notify you that it is installing the driver. The

driver, which was installed by the Setup program, will be automatically located and loaded.

Note that the Cypress Generic USB Driver is not a signed driver. Because of this, Win-

dows may present a warning dialog box. Choose “Continue” on the warning dialog. For

more information on driver signing go to the Microsoft website and search for “WHQL”

(Windows Hardware Quality Labs) or consult the Windows DDK documentation.

• The green light (BKPT/Monitor) on the Development Board should illuminate, indicating

that the 8051 Keil monitor code is loaded and running.

The driver, cyusb.sys, was automatically installed into the Windows\System32\Drivers directory

during installation of the DVK software. An .INF file was also created in the Windows\INF directory
