The image below shows my card reader. Above it is a CD/DVD unit that communicates via SATA. Cables out the back of the card reader are a Molex for power, a SATA, the USB 2.0 that runs to F_USB2 and a USB-A cable that connects to a USB 3.0 port on the back panel.
- What I gather from the USB Port document is that I have the ability to specifically select which ports to disable. For the 3x 2.0 ports, I can choose to select 2 of the 3 to disable, for example.
- How do the card readers communicate? It appears that the only choices are either USB or SATA. If it is USB, does that count as additional port(s)? If they do communicate over USB, then will disabling any (or all) of the USB ports on the reader prevent the card readers from functioning? (Crudely worded, I know)
- The 3.0 port on the card reader connects to a USB-A 3.0 port on the back panel. For 3.0 ports, is that counted as 1x or 2x?
- ESB 3.0 ports require 2.0 and 3.0 definitions. I assume this is what allows backward compatibility. Is it possible to disable the 3.0 definition and have the port function only as a 2.0?
- If I use a 3.0 port to connect to a hub with, say, 3x 3.0 ports, is that counted as 1x, 3x or 4x 3.0 ports? The reason that I ask is that when finished, my Hackintosh is going into a compartment under my desk with a door. It would be easier to connect a hub and place it external to the computer compartment rather than leaving the door open when I want to connect USB ear phones, for example.

To answer your points:
Those USB2.0 ports are probably connected to just one motherboard header. Usually this means they are actually a "hub". Because of this you cannot configure them, only the 1x motherboard header.
The card-reader is most likely connected to a USB header or port.
Yes, when you perform port-configuration you can chose to ignore USB3 and only have USB2 working.
As mentioned above, the ports on a hub have no 'identity', they are actually just the base port - which can be configured.
