Arasan provides the xHCI (eXtensible Host Controller Interface) driver for the USB 3.0 Host stack that makes it possible to communicate with the USB 3.0 device through the xHC hardware. The driver conforms to the latest USB 3.0 and xHCI specifications; it allows existing and new developments to easily migrate to the USB 3.0 specification. It is designed to seamlessly integrate into any OS design for an easy and cost-effective solution. It is also possible to validate the xHCI driver without the xHC hardware by using the Test harnesses developed for application layer and hardware layer.
