USB HighSpeed
 

I frequently get a notation that "this device could perform faster if you use it on a HighSpeed USB port" or some such.

But how do I find out which ports are high speed USB?

This is on a Win 7 machine with quite a few USB ports scattered all over the place...

Are they colour coded? (plastic tag inside the socket) In know the new Lenovo Stinkpads are.

no, they all seem to white inside

is there any way to run a software app to test them?

From Wiki USB3.0 : "There have been many reports of USB 3.0 equipment only transferring data at USB 2.0 speed, usually with a message "This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port". This has been due to several causes, including drivers, certain cables specified as USB 3.0 (problems disappeared when a different cable was used), order of starting equipment, equipment needing to be disconnected and reconnected, and overclocked computers."

Other than speed, the dual-directional data transfer allows use of an asynchronous USB D to A. This solves the problem of dueling DAC clocks which has plagued earlier USB DACs for high quality audio applications.

interesting - I did not think the device was 3.0 but...

I wish Apple would go to USB 3 Instead they adopt some lame ass thunderbolt. Asshats.

for some reason there are "Enhanced" ones - high speed and (maybe) non-highspeed ones -- is that what this means?

or does it just have the "Standard OPenHCD" ones for compatibility or something?
