USB_AH(7M)USB_AH(7M)NAMEusb_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.
