USB Device Stack (USBware Components)

USB Device Stack

» A part of USBware: Embedded USB Software solution
Jungo provides a complete, small footprint, high quality USB (Universal Serial Bus) function/device stack, including Application Programming Interfaces (APIs) and services that enable software and device manufacturers to incorporate standard USB device/function connectivity in their embedded devices.

Background
USB provides an expandable, hot-pluggable Plug and Play serial interface that ensures a standard, low-cost connection for peripheral devices such as keyboards, mice, joysticks, printers, scanners, storage devices, modems, and video conferencing cameras.

The Jungo USB device stack is divided into three main layers: the USB Core Layer, the Function Driver (FD) and the Device Controller Driver (DCD). Beneath these layers lies the Hardware Controller, which is an environment-specific USB hardware controller.

The Jungo Operating System (JOS) is a special abstraction layer between Jungo's multi-platform device stack and the host operating system (OS).
