USB_AH(4M) STREAMS Modules USB_AH(4M)

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(4D)) and below
an Audio Control class driver instance (see usb_ac(4D)). It
translates the HID specific events to the events that are supported
by the Solaris audio mixer framework.
