CyUSB.sys general purpose driver

Last Updated: August 29, 2011

Where to find the new CyUsb.sys USB General Purpose Driver?


The new General Purpose Driver is included in the SuiteUSB SDK. It is compliant to the Windows Driver Model (WDM) and is WHQL compatible. It also includes support for PnP, remote wake-up, customizable GUID, and power management level S4. The driver can be used with general purpose applications that use control, interrupt, bulk or isochronous transfers. Note that CyUSB.sys is a generic USB driver which means that it assumes the device bound to it has single interface (can have many alternate settings).

Note:- After installing the SDK you can find the drivers in C:\Cypress\Cypress Suite USB 3.4.6\Driver\bin separated into folders based on the OS and hardware platform.
