2.2 Compatibility with Earlier EZ-USB Development Kits

This EZ-USB Advanced DVK has the ability to co-exist with older EZ-USB Development Kits. This

DVK uses the same basic directory structure as the older Development Kits.

The only conflict with older development kits is with driver binding. The older DVK used a different

device driver - the EZ-USB General Purpose Driver. That device driver is bound to the VID/PID of

the EZ-USB FX2 chip: VID=0x04B4 and PID=0x8613. The EZ-USB FX2LP shares the same PID.

This conflict only applies when the FX2LP enumerates in "Default USB Device" mode (i.e. RENUM

bit is not set and there is no VID/PID stored in EEPROM). You can bind FX2LP to the new Generic

USB driver by right-clicking on it in device manager and choosing "update driver". This should

present you with two driver choices. Choose the driver where the description contains "FX2LP".

2.3 Installation Instructions

Start by collecting the following materials:

• Installation CD

• The EZ-USB Advanced Development Board

• USB A-B Cable

• A Development Platform (PC) with USB support

Apple Macintosh Note: The EZ-USB Development kit is designed to work only on a Windows

based PC. If you are developing on a Mac, an application note titled “EZ-USB Development for

Mac OS” is available on the Cypress Website (www.cypress.com)

2.4 Verifying that the host PC supports USB

Almost all PCs manufactured after 1997 include full-speed USB host controller hardware. As of

mid-2003, most but not all PCs include a USB 2.0 high-speed host controller. Drivers for full-speed

host controllers have been distributed with Windows 98 and later versions of Windows. High-

speed drivers are a different matter. Support for high-speed USB did not ship in the initial releases

of any of the DVK supported OSs. High-speed drivers for the supported OSs are available as fol-

lows:

• Windows 2000 - Install Service Pack 4 or later

• Windows XP - Install Service Pack 1 or later

• Windows ME - For PCI add-in adapters, drivers may be available from the adapter's man-

ufacturer. There is no driver support available for the Intel integrated high-speed host con-

troller (i.e. ICH4). Microsoft has not and will not release high-speed drivers for Windows

ME. For this reason, use of Windows ME is discouraged for high-speed peripheral devel-

opment.
