Cypress USB Drivers for EZ-USB Kits
6.2.1 Binding Cypress USB Driver to EZ-USB Development Board
The EZ-USB (FX1/FX2LP) development board supplied with the kit is used to bind the signed
Cypress USB driver. Following are the steps to bind the driver:
1. Disconnect the USB A-to-B cable between the J1 connector and the PC USB Host port, if con-
nected previously.
2. Verify the following default jumper settings for the EZ-USB FX1 and FX2LP boards.
FX1: Short on JP1, JP2, JP3, JP5, JP6, JP7, JP8, and JP10.
FX2LP: Short on JP1, JP2, JP3, JP5, JP8, and JP10. Open JP6 and JP7.
The functionality of each of these jumpers is explained in Chapter 3 .
3. Verify if SW2 is switched to the side, marked as NO EEPROM .
4. Re-connect the USB A-to-B cable between the J1 connector and the PC USB Host port.
5. The EZ-USB FX1 (0x04B4/0x6473) and FX2LP (0x04B4/8613) boards enumerate with the
default Fuse ROM VID/PID.
6. The Windows hardware wizard window pops up allowing you to update the corresponding driver
path, as shown in Figure 6-4 .
Table 6-1. List of VID/PID used in EZ-USB Kits
S.No VID/PID Functional Description
1 0x04B4/0x8613
EZ-USB FX2LP Fuse ROM VID/PID.This is the initial VID/PID when
the board is powered, with the SW2-NO EEPROM setting as the
default combination
MOBL-USB FX2LP18 Connect Mode. Uses LP18_dvk.iic as the
default image in EEPROM to enable the DPTR register and enumer-
ate with this VID/PID
2 0x04B4/0x6473 EZ-USB FX1 Fuse ROM VID/PID
3 0x04B4/0x1004
Firmware examples in the EZ-USB kits use this combination except
for the
hid_kb example, which uses 0x04B4/1005.This example
requires the Windows HID-Class driver and does not require a
Cypress USB driver
4 0x04B4/0x1003
This is used by the Cystream firmware example available in Suit-
eUSB 3.4.7 supplied along with this kit. Download
CYStream.hex
from
C:\Cypress\Cypress Suite USB 3.4.7\Firm-
ware\CyStreamer
using Cyconsole or CyControlCenter utility
and test it using Streamer applications available in SuiteUSB.The
procedure to download a firmware .
