Driver Overview51Driver Overview

The CYUSB3.SYS driver is licensed for distribution ONLY with Cypress USB products andproducts that employ Cypress USB chips. CyUSB3.sys is a kernel mode USB function driver,it is capable of communicating with any USB 2.0 andUSB3.0 compliant devices. The driver is general-purpose, understanding primitive USB commands, butnot implementing higher-level, USB device-class specific commands. For this reason, the driver is notcapable, for instance, of interfacing a USB mass storage class device to the Windows file system.Please note that this release does not include the USB3.0 bulk streaming interface. The driver would be ideal for communicating with a vendor-specific device from a custom USB applicationor to send low-level USB requests to any USB device for experimental or diagnostic applications. In order to use the driver to communicate with a device, Windows must match the device to the driver. The class library, CyAPI.lib and Cyusb.dll, provides a high-level programming interface to the driver. Thishelp file documents the low-level, more cumbersome and explicit programming interface.The driver supports following operating systems and platform.1. Windows XP 32 bit2. Windows Vista 32/64bit3. Windows 7 and 32/64 bit 4. Windows 8 Beta 32/64 bitCypress signed CyUSB3.sys driver for following Cypress VID/PID pairs.1. VID_04B4&PID_00F02. VID_04B4&PID_00F13. VID_04B4&PID_00F34. VID_04B4&PID_4720

Please note, the driver is signed for above mentioned pairs of Cypress VID/PID. If you modify CyUSB3.inf to add your own VID/PID, the driver will become unsigned. However, Windows OS will allow to installthe unsigned driver with warning messages on 32-bit and 64-bit platform. You can go for WHQL drivercertification with your own VID/PID once your product is ready.
