alright, so USB (from experience not official.) black tab is everything up to 2. USB 2 is white tab, USB 3 is blue tabs, and yellow is fast charging, but they some times do data. I know on my case (corsair airflow 4000d.) the front side bus has yellow tabs, but has reasonable read/write speeds. I don't use any fast charge wires and don't have any devices with that standard anyway.
So long story short: as long as the case is provably built after the year 2000, it's a 2.0 spec. As for the hardware monitoring: it's either HWinfo, or AIDA64. Those are the two big ones, BUT you can also get all that information through your GPU software these days.
