Thanks
The ASIO driver we're putting in box isn't an ASIO4All-type wrapper, so it's tied to the new low-latency USB Audio Class 2 driver.
There's no audio class standard for PCIe or Thunderbolt, so those will still need to be vendor drivers. I looked into what it would take to define a standard a long time ago, and it was WAY too much work for me to even consider at the time. Maybe in the future.
