Jungo provides a complete, small footprint, high quality USB (Universal Serial Bus) Host Stack, including Application Programming Interfaces (APIs) and services that enable software and device manufacturers to incorporate standard USB Host connectivity in their embedded devices.

The USB Host Stack is a part of Jungo's USBware product.

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

USB is natively supported in almost all desktop operating systems (Windows, Linux) while other embedded operating systems or firmware that need USB support require a dedicated USB stack, available from Jungo.

The Jungo USB Host stack consists of three logical layers communicating through two interfaces. The upper layer is the Device Driver layer, representing the different class drivers. The other two layers are responsible for abstracting the USB device to this device driver layer. These layers are the USB Driver layer (USBD) and the Host Controller Driver layer (HCD).
