Cypress Semiconductor Corp. has announced the release of its VxWorks USB host driver that support the SL811HS embedded host/peripheral controller, providing VxWorks developers with the ability to add USB host functionality to embedded system applications, such as cell phones, MP3 players, network appliances, and PDAs.

Wind River's VxWorks RTOS supports the Open Host Controller Interface (OHCI) and the Universal Host Controller Interface (UHCI) specifications for USB host controllers, which are typically implemented in a PC architecture and environment.

Since the SL811HS is a memory-mapped device, the driver allows the VxWorks host stack to provide USB host support without realizing that there is a non-OHCI/UHCI type host controller.

With the SL811HS, Cypress claims to be the first-to-market USB embedded host controller, offering a dual-role port that can function as either a USB host or peripheral supporting both full- and low-speed USB devices.
