Hspa Data Card Wmc Bus Driver For Windows 8.1

The USB Audio Class is defined such that if a USB device follows the specification, a PC host will treat it as a sound card. As shown in Figure 4, this is accomplished by adding an audio function driver to the embedded device. This function driver provides both an audio interface and a MIDI (Musical Instrument Digital Interface) interface to a sound manager, which in turn can connect to a microphone, speaker, or other audio gear, such as a musical instrument. Thus audio and MIDI streams can be transferred over a USB link rather than using audio or MIDI cables. This uses the USB isochronous mode of data transfer.
