USB 2.0 Audio

Description
Recently I connected a USB audio interface to an Openindiana machine and found out it wasn't working because it required USB audio 2.0 (Linux, MacOS/iOS and recent versions of Windows 10 have it).
I'm aware there probably isn't a lot of interest but here is the standard just in case:

Out of curiosity, what audio devices did you have that were requiring that?

Apparently all of this manufacturer’s class compliant USB devices are USB 2.0 only.
If this wiki page is anything to go by there seems to be a mix of USB 1.1 and 2.0 devices out there:

I wouldn’t expect many simple dual channel audio interfaces to be implemented as USB 2.0 as they don’t benefit much from the additional features (primarily channel count & latency).
