Jungo offers Human Interface Device (
HID) class and function drivers, which provide a complete embedded solution for host and device communication with HID USB devices, such as keyboards, pointing devices (e.g. mouse devices; joysticks), front-panel controls, etc.
The HID PC USB Communication Drivers support the host-side communication with HID USB peripherals, while the
HID USB Function Drivers provide the required device-side USB HID implementation for such peripherals.
The HID class/function drivers utilize Jungo's generic USB HID Class/Function Driver Libraries (respectively), which provide common USB HID functionality and enable developers of new HID class/function drivers to focus only on the unique additional functionality required for their specific devices.
Background
The Universal Serial Bus (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.
A USB Class Driver is a Logical Device Driver (LDD), which controls
USB devices that provide common functionality and are implemented
in compliance with a specific device class.
A USB Function Driver is a driver implemented within a device in
order to handle the device-specific functionality of a standard
or custom USB device function. This driver provides the counterpart of the USB Class Driver.
Jungo's USB HID Class Drivers and USB HID Function Drivers (keyboard, mouse, joystick, etc.) are fully functional USB HID class/device drivers (respectively). These drivers utilize Jungo's USB HID class/function driver libraries,
which implement common USB HID class/device functionality and allow the specific HID class/function drivers to focus on the required additional device-specific functionality.
The USB HID class library and drivers are part of USBware's USB Host Stack, which offers a complete solution for USB host communication for embedded systems that do not natively support USB.
The USB HID function library and drivers are part
of USBware's USB Device Stack, which enables software and device manufacturers to incorporate standard USB device/function connectivity into their embedded devices.
The USB HID class drivers implement the USB Host Stack's outer interface and are responsible for relaying information between the host and the USB device. The HID class drivers communicate with the device via their USB Device Stack counterparts - the HID function drivers, which provide the device stack's upper layer (see the System Architecture diagram).
