Dragonfly DAC is async DAC, not adaptive one, which use async mode for
isochronious transfers (not very common mode, but standard one for
sure, since USB 1.1) and local clock source for DAC itself.
Also, it squeeze maximum from USB 1.1 (96/24) without being USB 2.0
audio device, as far as I know, but I may be wrong here.
