The USB audio device driver supports isochronous USB devices such as USB audio speakers. Each USB audio device is represented as the following interfaces: audio control and audio streaming. Although these interfaces are associated with the single device, the interfaces are treated as separate devices virtually.
The USB Audio class system driver (Usbaudio.sys) is an AVStream minidriver that provides driver support for audio devices that comply with the Universal Serial Bus (USB) Device Class Definition for Audio Devices.

Notice that when you select Positive Grid USB Audio Device Driver v4.80.0 in the list of apps, the following information about the application is available to you: Safety rating (in the left lower corner). The star rating tells you the opinion other people have.
- USB Device Driver Open the Device Manager console (Win + R - devmgmt.msc). Your unknown device is likely to be found in one of the following sections of the Device Manager: Universal serial Bus controllers.
The USB Device Class Definition for Audio Devices specification (release 1.0) is available at the USB Implementers Forum website. Usbaudio.sys supports a subset of the features that are described in the USB Audio specification. In addition to Usbaudio.sys, there are several other kernel-mode audio components in the Windows Driver Model (WDM). For more information, see Kernel-Mode WDM Audio Components.
In Windows 98 Usbaudio.sys introduced support for USB devices such as speakers and microphones. Support for MIDI devices was added in Windows Me.
When an audio device identifies itself as USB Audio-compliant during Plug and Play device enumeration, the system automatically loads the USBAudio driver to drive the device. USBAudio drives the device directly, without the aid of a proprietary adapter driver. This means that a device that complies with the USB audio specifications requires no proprietary adapter driver.
Microsoft recommends that hardware vendors use the USBAudio driver for their USB Audio devices instead of writing proprietary adapter drivers.
In Windows 98, the USBAudio driver supports the following features:
All Type I formats (except 8-bit signed PCM)
AC-3 Type II format
Synchronization types synchronous and adaptive
Multichannel devices
However, USBAudio in Windows 98 does not support:
8-bit signed PCM format
MPEG Type II format
Type III formats
USB MIDI
WAVEFORMATEXTENSIBLE wave format (USBAudio uses packed WAVE_FORMAT_PCM for 24-bit data instead.)
In Windows 98 Second Edition (SE), Windows Me, and Windows 2000 and later, USBAudio supports all the same features as Windows 98, with one exception: USBAudio supports WAVEFORMATEXTENSIBLE but does not support packed WAVE_FORMAT_PCM for 24-bit data.
In Windows Me, and Windows XP and later, USBAudio supports all the features that are supported in Windows 98 SE and Windows 2000. In addition, Windows Me and Windows XP support USB MIDI but do not support USB MIDI Elements.
The following figure shows the driver hierarchy for a USB audio device. All of the driver components shown in the figure are provided by Microsoft with the operating system.
