NAME

6       usb_ah - USB audio HID STREAMS module
7

DESCRIPTION

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