usb_ah - USB audio HID STREAMS module
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.
