Help me understand my USB?

[geezer]

I have a ASUS K8V SE Deluxe MOBO. It has a maximum of 8 USB2 ports, 4
built into MOBO, 4 available on a 1X4 USB 'module' with cables that
connect to two headers on the MOBO. One header is labeled USB56, the
other is labeled USB78. As far as I know, all 8 ports work, because
at various times, I have connected peripherals such as printer(s) and
camera(s) to them.

This is my question. I looked in Device Manager and it shows the
following:

USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
VIA Rev 5 or later USB Universal Host Controller
VIA Rev 5 or later USB Universal Host Controller
VIA Rev 5 or later USB Universal Host Controller
VIA Rev 5 or later USB Universal Host Controller
VIA USB Enhanced Host Controller

I look at these and ask - how do I get my 8 ports out of all this?
5 hubs is certainly an odd number, and I don't mean numerically.
I guess the 4 VIA Rev Controllers could relate to the 4 on-board USB
ports.
I have no idea what the last one is.

Anyone?

Thanks.

Each controller can handle two sockets in your configuration.
The last entry means you have USB 2.00 enabled.

If I can bother you one more time - why do I have FIVE 'USB Root Hubs'
in the Device Manager list. I have EIGHT ports. I have just ONE USB
peripheral device connected right now. The fact that I have FIVE
makes no sense to me - to you?

Thanks\\Geezer

Look at the first 5 that you have listed, the rest are controllers. In the
first five, under Device manager, explore the properties/power tab of each,
see if you have eight, might be for some interesting viewing.

1 - 4 say each have '2 ports available'. The fifth says '8 ports
available'. Does this make sense?

Thanks

Of course.Think about it as I tried to explain(my fault,I wasn't
clear).
If you did NOT have USB 2.00 enabled an installed you would only see 2
entries for each e.g

A USB device needs a Controller and a HUB in Software but each of
these can handle 2 ports/sockets so dat makes 4 entries in the device
mangler<sic>(Dem ting on the back/side or front of the box.)


Once USB 2.00 is installed it adds a double set of entries usually 2
more under it's own section.
Thus looking like 5 Entries.

These communicate with the normal USB 1.00 entries and add to
and,"Enhance" the USB 1.00/1.01 protocols and get you the way better
speed of USB 2.00 total.

Note:This is the best I can do after having a good night out and

Yes, it is common that when there's USB2, there will be
another entry for "Enhanced" controller and hub to designate
that, while the actual ports are listed with the more basic
entries, the 4 you note. That's fine, why such an interest
unless it isn't working?

If there were some logic behind it, might be useful in the
future but it's just windows, like memorizing random
numbers.

Shep -

I thank you for taking the time to help increase my knowledge. I was
curious but at the same time fearful that just maybe my XP was wasting
resources or generating wasteful/conflicting activities. Been known
to happen.

Any it is a dead issue now so our detractor can turn to other things.

And one day I will find a use for the value of X
