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.

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.
