Hi all… I have a problem streaming via USB B to Pro Tools 11 on Windows 7 64. When i connect the QU16 everything works fine, I can stream my Windows audio to the QU and record via the QU in Audacity. I’m normaly running Pro Tools 11 with my MBox 2, and it works flawlessly. When I try to open Pro Tools 11 with the QU connected instead it takes ages to start PT. In the Setup screen of PT I can see the QU Asio, also in the I/O screen. When I try to start a new session it takes ages to load. I created 1 new mono channel trying to record Channel 1 from QU. When I record enable the channel, there’s no moving in the level meter. When I start recording, there’s an error that there wouldn’t be enough CPU-Power. As I stated above, with MBox 2 it works without problems, so I think there’s something wrong with the windows driver of QU. Has anyone had the same problems? ---

I downloaded Cubase 7 Elements trial and it works totaly fine, both streaming to and from QU. So it’s definetly a Pro Tools problem. Any idea from the A&H people?
