You connect a high-speed USB 2.0 audio device to a computer that is running Windows Server 2008 or Windows Vista. When you operate the USB audio device, you notice that the CPU usage is greater than the CPU usage of the same device when the device is connected to a Windows XP-based computer. You also notice that the CPU usage is greater than the CPU usage of a similar USB audio device that connects as a full-speed USB device. Additionally, you may experience skipping in audio playback from the high-speed USB 2.0 audio device.
Note: The increase in the CPU usage may be especially high in a low-performance system.
