Can someone help me understand USB cable standards, which seem ambiguous in their naming of standards and shape of the plugs and sockets?
I want to buy a Male A to Male B USB cable to interconnect an Innuos ZENmini MK3 streamer/server to the DS DAC. The Innuos site describes the USB requirements in two statements. Under “connectivity”: USB 3.0. Under “audio outputs”: USB Audio 2.0 supporting USB Audio Class 2. PSA describes itself as a “USB 2.0 audio device”.
The source of my confusion relates to the shape of the Male B end of the cable, which looks like it need be type 2.0 on the DS DAC, not 3.0 as Innuos describes under “connectivity”. The Male A end looks the same for 2.0 and 3.0 standards (but are they really?). What’s up with that?
To complicate further, ultimately I will likely want to connect the Innuos unit to an AirLens with the same cable. Any idea whether the socket on the AirLens will accept a 2.0 Male B plug, or a 3.0 one?
An alternative approach might be to interconnect the Innuos and DS DAC (later AirLens) via an audio quality RJ45 cable.
