NAME
usb_ah - USB audio HID STREAMS module DESCRIPTION
The usb_ah STREAMS module enables the USB input control device which is a member of the Human Interface Device (HID) class and provides support for volume change and mute button. The usb_ah module is pushed on top of a HID class driver instance (see hid(7D)) and below an Audio Control class driver instance (see usb_ac(7D)). It translates the HID specific events to the events that are supported by the Solaris audio mixer framework. FILES

NAME
hid - Human interface device (HID) class driver SYNOPSIS
keyboard@unit-address mouse@unit-address input@unit-address:consumer_control The hid driver is a USBA (Solaris USB Architecture) compliant client driver that supports the Human Interface Device Class (HID) 1.0 speci- fication. The Human Interface Device (HID) class encompasses devices controlled by humans to operate computer systems. Typical examples of HID devices include keyboards, mice, trackballs, and joysticks. HID also covers front-panel controls such as knobs, switches, and buttons. A USB device with multiple interfaces may have one interface for audio and a HID interface to define the buttons that control the audio. The hid driver is general and primarily handles the USB functionality of the device and generic HID functionality. For example, HID inter- faces are required to have an interrupt pipe for the device to send data packets, and the hid driver opens the pipe to the interrupt end- point and starts polling. The hid driver is also responsible for managing the device through the default control pipe. In addition to being a USB client driver, the hid driver is also a STREAMS driver so that modules may be pushed on top of it. The HID specification is flexible, and HID devices dynamically describe their packets and other parameters through a HID report descriptor. The HID parser is a misc module that parses the HID report descriptor and creates a database of information about the device. The hid driver queries the HID parser to find out the type and characteristics of the HID device. The HID specification predefines packet formats for the boot protocol keyboard and mouse. /kernel/drv/hid 32-bit ELF kernel hid module /kernel/drv/amd64/hid 64-bit ELF kernel hid module /kernel/drv/sparcv9/hid 64-bit SPARC ELF kernel hid module /kernel/misc/hidparser 32-bit ELF kernel hidparser module /kernel/misc/amd64/hidparser 64-bit ELF kernel hidparser module /kernel/misc/sparcv9/hidparser 64-bit SPARC ELF kernel hidparser module See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Architecture |SPARC, , PCI-based systems | +-----------------------------+-----------------------------+ |Availability |SUNWusb | +-----------------------------+-----------------------------+ cfgadm_usb(1M), attributes(5), usba(7D), virtualkm(7D) Writing Device Drivers STREAMS Programming Guide Universal Serial Bus Specification 1.0 and 1.1 Device Class Definition for Human Interface Devices (HID) 1.1 System Administration Guide: Basic Administration http://www.sun.com/io None.
