No such thing as USB2.0 ports.
All usb ports can be USB2 or 1.1 depending on motherboard USB support and OS
usb support.
If USB2 is enabled in the bios and the os has support/drivers then the ports
will work as usb2.
If not then 1.1
On a board with no USB2 support so called usb2 ports will work as usb 1.1
So called usb2 ports will work as 1.1 as well if the board has bios setting
for usb 2.0&1.1, and if there is a setting for only usb 1.1 then they will
only work as 1.1
I have installed loads of "usb2" ports and loads of "usb1" ports and they
have all had the same connections.
If sold as usb2 ports then most store charge more.
Belkin charge more for ports sold as high speed usb(or usb2)ports that are
exactly the same as "usb1" ports.
If I fitted "usb1)ports and connected my usb2 camera or other items then
they work exactly the same, no faster, no slower, no difference.
(With my motherboard usb1.1&2.0 enabled and usb2 drivers)
 
I have four unwanted sets of USB ports that came from motherboards
supporting only usb1.1 and from others supporting usb1.1 and 2.0 and they
all work with 1.1 and 2.0

Technically, the USB2 specification, adds the requirement for an extra
protective ground wire, and tightens the cable impedance specification.
Connectors marketted as USB1.1, will not necessarily run reliably at USB2
speeds, and may well be out of spec.

Sure but what if the onboard header does not even use the extra wire?
All the so called USB2 one I have used never have or even use the extra wire
and they all work without problems.
I have swapped "1.1"ports with "2.0 "ones and they all had the same results.
All boards I have worked with have had two rows of for wires, all connected
and have never had an extra wire.

They usually make the extra connection to the _case_.

Try it with an accessory attached that is close to the cable length limit.
The difference willthen become obvious.

Just to set the record straight:

USB2.x has a higher potential data rate than USB1.x and the cable specified
for reliable data transfer with USB2.x is NOT the same specification as the
cable that is supplied with equipment designed for USB1.x.

For those that require additional USB2.x back plates complete with USB2.x
specification cable and connectors for use with a USB2.x equipped
motherboard then see this link.
