Quote "Adaptive Mode USB: The T1 uses adaptive mode USB that relies on your computer to control the flow of data streaming from the USB port. " (emphasis added)

I always thought that "adaptive" was the short way of saying adaptive isochronous. I never heard of any other type of adaptive.

I always thought isochronous was 48k.

Foobar 2000 is one way of of getting "your computer to control the flow of data streaming from the USB port" so that it plays 96k (and 192?, and definitely XRCD rips, with the right add-in).

The correct description of the T1 and other USB audio products is the responsibility of their respective manufacturers - and they have a real responsibility, at least in the UK, under the description of goods act. In other parts of the world there may not be such legalities?

At least I can sleep at night knowing that I have described the Bitzie correctly. Approve

You do not see a type called Asynchronous do you?

Found the correct link and quote: "These endpoints cannot be synchronized to a start of frame (SOF) or to any other clock in the USB domain."

Therefore the assumption of its validity is erroneous Question
