Distributing General purpose driver (ezusb.sys) with a custom product

Last Updated: December 31, 2011

Can the Cypress general purpose driver,ezusb.sys be distributed along with a Custom Device?


Cypress does not recommend that to distribute or ship ezusb.sys with your final product.

The general purpose driver was created for demonstration purposes, and is not production ready. There may be corner cases (e.g. power management) that may not be completely handled properly for your own application. Please distribute the driver at your own discretion, always abiding by the software license agreement distributed with each development kit. At the very least, Cypress recommends that you remove all Cypress manufacturer strings (if any), etc. if you do indeed plan to distribute ezusb.sys.

The updated driver CyUSB.sys can be used instead, for the development and distribution purpose.
