Cypress Releases USB Host Controller Driver for Linux.Business Editors/High-Tech Writers SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--May 22, 2002 Enables Linux Host Stack to Provide Embedded USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. Host Support for Applications Such as Cell Phones, MP3 Players and PDAs; Leverages Cypress's SL811HS USB Host/Peripheral Controller Cypress Semiconductor Cypress Semiconductor is a semiconductor design and manufacturing company. It began operations in 1982 and listed publicly in 1986. Two years later, the company shifted over to the New York Stock Exchange under the symbol, (NYSE: CY). Corporation (NYSE NYSE See: New York Stock Exchange :CY) -- the leader in USB technology -- today announced the release of its Linux USB host driver supporting the SL811HS embedded host/peripheral controller. This driver will provide Linux developers the ability to add USB host functionality to a variety of embedded system Any electronic system that uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Such systems generally use microprocessors, or they may use custom-designed chips or both. applications, such as cell phones, MP3 players, network appliances and PDAs. "Cypress continues to demonstrate its leadership in USB supporting emerging markets and platforms such as embedded Linux," said Jeff Chang, product marketing manager for Cypress's Personal Communications Division. "The release of this host controller driver will enable developers to add USB host functionality to their embedded system designs running Linux." Currently, the Linux 2.44 kernel supports the Open Host Controller Interface A host controller interface is a register level interface which allows a host controller for USB or FireWire to communicate with the operating system of a personal computer. (OHCI OHCI - Open Host Controller Interface ) and the Universal Host Controller Interface (UHCI UHCI Universal Host Controller Interface ) specifications for USB host controllers, which are typically implemented in a PC architecture and environment. Since Cypress's SL811HS is a memory-mapped device, the release of this new driver allows the Linux host stack to provide USB host support without realizing that there is a non-OHCI/UHCI type host controller. This driver enables engineers to bring their products to market more quickly. About SL811HS The SL811HS is Cypress's 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. Pricing and Availability The Linux USB 2.0 driver and source code are available now. To download the source code, visit: http://www.cypress.com/press/linux.
