I have a couple of new USB 3.0 devices which connect to my USB 3.0 ports via the new "Blue" USB 3.0 cables that end in what looks like a USB 2.0 Type A connector. Indeed, the USB 3.0 devices will also work in the USB 2.0 ports.
So, I have some USB 2.0 extender cables. While I obviously can run the USB 3.0 devices over the USB 2.0 cables, will I be able to get the USB 3.0 speeds or do I need to get the specific USB 3.0 cables - to get the maximum transfer speeds?
It's not the cost - you can get the cables cheap. It's just understanding how the end-to-end system works (and the "in case of emergency - break glass" effect).
