two for receiving, two for transmitting, each 5gbit/s for a total of
10gb/sec.  the connector and thus the pinouts are rotatable by 180
degrees so the pinouts on the first 12 pins (top row) are *identical*
layout to the second 12 pins (bottom row) except in the reverse order.
D+ and D- (the USB2 pins) are *missing* on one row of the receptacle
so that you don't connect them up twice (which would be bad).

you *may* be thinking of USB 3.0 which is connector-compatible with
USB 2.0 and is what you find on most laptops and desktop computers
these days:

that is *only* one set of (5gbit/sec) tx-rx differential pairs.

scared me for a minute that i'd messed it up... :)
