USB 2.0 Controller

I've just got my new motherboard which claims to have 4xUSB2.0 ports.
However, using the SiSoftware 2004 utility to examine my motherboard
(Mainboard Information category in the software), I apparently have 4 USB
controllers - only one of which is for USB2.0:

USB Controllers 1-3
Model : VIA Technologies Inc VT82xxxxx UHCI USB 1.1 Controller (All VIA
Chipsets)
Version : 1.10
Interface : UHCI
Channels : 2
Speed : 48MHz
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps)
Legacy Emulation Enabled : No

USB Controller 4
Model : VIA Technologies Inc VT6202 USB 2.0 Enhanced Host Controller
Version : 2.00
Specification : 1.00
Interface : EHCI
Channels : 6
Companion Controllers : 3
Supported Speed(s) : Low (1.5Mbps) Full (12Mbps) High (480Mbps)
Addressing Support : 32-bit
Legacy Emulation Enabled : No

Has this board then really got only 1xUSB2.0 port and 3xUSB1.10s? Or does
the board use whichever controller it needs to given the specification of
the device? Or is Sandra 2004 just misreading the hardware? Your thoughts
please.

Do not consider Sandra reports, simply discard them in favor of
already-known specs. Your motherboard manufacturer has specs, trust
them. Read the manual, it should clearly show where and how many USB2
ports you have.

The way USB 2.0 drivers are written is that they are 1.1 drivers with 2.0
'modifiers' sitting on top. The key word in Sandra's report is "Channels: 6"
in USB2.0 section. I suspect your mobo actually has 6 USB2.0 ports, 4 on the
back and 2 headers (8 or 10 pin connector) somewhere on the mobo (the pins
could be missing in some versions of the board).

Thanks for clearing that up - that confirmed an inkling I had - the
motherboard manual does specify that it has 2 extra USB headers.

While I'm here - being new to the hardware side of a computer - how do I fit
a USB "card" I've got to the motherboard, to the header connection? I have I
think (its not with me) a 2 port USB2.0 - not card - but thing with just a
female rectangular connection on the end of it. It has, I think, 10 pins,
some of which are blocked in so you can't fit them over a corresponding 10
pin connector. In my old system, it fitted over in an almost "S" shape
pattern pin connector on the mobo, but it doesn't seem possible with this
header. Have I got the wrong end of the stick? Or is there another way to
connect it up using another middleware connector or something?

If the USB bracket came with the mobo then surely it should fit?

Sorry, to make it clearer from my previous post - the USB "bracket" came
from my old system.

OK, you can rearrange the wires in the 10 way connector block according to
the mobo manual. There are usually only two different arrangements. Red 5V
wires next to each other or diagonally opposite.

Red * * Red
White * * White
Green * * Green
Black or key * * Black or key
Black or key * * Black or key

or

Red * * Black or key
White * * Black or key
Green * * Green
Black or key * * White
Black or key * * Red

Note: the blocks in keyed locations are removable, you can push them out
from behind.

Oh right, I see - those "keys" push out do they, hmm, OK, thanks a lot, I'll
read up in my mobo manual and give it a go later, thanks very much : )
 
OK, I've looked in my motherboard manual and I have a 9-pin USB45 header. My
USB bracket has the second layout you described.

The manual's diagram is:

USB_PWR ** USB_PWR
P-4 ** P-5
P+4 ** P-5
GND ** GND
Key ** Dummy

which I guess means you first diagram, which is not compatible - or do all
the wires push out? I can't figure how to lift them out - there's no obvious
mechanism to do so. I think I'll have a google for any pictures as well
though.
