Hi Frank, This is James from Conexant. We are actually in the process of designing a High-Speed USB Audio device. I just saw this thread by chance so I'm a little late to the game here. I noticed you mentioned USB 2.0, but the list took this discussion into "High Speed" vs "Full Speed". When you say add USB Audio 2.0 support in Windows - is this adding support for the extended feature set in the USB Spec? or does this also include supporting devices that are "High Speed" vs "Full Speed"? In any case, our device will certainly be running high-speed, and may also include additional controls available/described in the USB 2.0 spec that aren't in the USB1.0 spec Thanks, James From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Frank Yerrace Sent: Tuesday, October 20, 2009 6:24 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Why would you want USB Audio 2.0 in Windows? There are occasional questions on this list about USB Audio 2.0 support in Windows. We (the Windows sound team) are curious to hear specific reasons- scenarios, business, features, etc.- that would be enabled if USB Audio 2.0 support was included in Windows. Are any of you willing to share this? The more specific you can be, the better. If you do not want to share with the entire list then feel free to send a message to me directly.
