USB 2 - "The device can perform faster"

I'm rebuilding my Gigabyte GA-7VAX based system because, as a development
PC, I've
installed so much crap over the year that it's taking forever to start-up.

Anyway, basic installation of Windows XP Pro with SP2 carried out with all
USB 2 devices unplugged. I've taken an image of this basic set-up.

I've got all six USB ports available: the two on the motherboard plus the
extra four connected to a four port panel on the back of the PC. When I plug
in my high-speed four port USB hub in, Windows XP reports "The device can
perform faster". When I click the button to display which high speed ports
I've got, it lists all six of the ports described above :-)

The motherboard is USB 2 so what's going on? Why does Windows XP says "The
device can perform faster" and then go on to indicate that the USB ports
I've plugged it into are already high speed...

Got me flummoxed <grin>

BTW - I've not installed any Gigabyte specific drivers yet. Windows XP seems
to support all the devices "out of the box". I only tend to install
motherboard drives if there's a problem. There isn't a USB 2 driver for
Windows XP anyway AFAIK.

Not critical - just annoying...

Thanks, Rob.

Hmm, interesting thing here. I've just been looking at the USB devices in
device manager. There are *four* USB root hubs listed:

o USB Root Hub: 2 ports (this one shows the generic hub connected)
o USB Root Hub: 2 ports
o USB Root Hub: 2 ports
o USB Root Hub: 6 ports

Now that last 6 port one is a bit strange. I certainly don't have 12 ports
on the motherboard :-)

I suspect that on the motherboard, there are three USB root hubs which are
somehow connected together onto the last root hub. This gives the 6 ports.

And for some reason, Windows XP thinks the three "real" USB root hubs are
USB 1 whereas the "joined" hub is USB 2. Hence the reason it suggests I plug
it into this joined hub. Of course, I can't because that joined hub doesn't
really exist outside of the motherboard.

Cheers, Rob.

you ARE having problems....

Yes but there aren't any USB drivers available from Gigabyte for USB. They
say "See Microsoft".

I get this message when I plug an USB 2.0 device into the front USB
ports on my computer, because the header for these ports is USB 1.1 on
my Gigabyte GA-7VA motherboard. Check and see if the extra ports on the
PCI slot backplate are connected to the rear headers or the USB 1.1
front headers.

I've had a look at the manual, and there are 4 USB headers along the
bottom of the motherboard (two groups of two). They are ALL USB 2.0,
unlike my GA-7VA board. My suspicion now would be that your USB hub is
one of the many varieties of USB 2 that were produced that do not
perform at the speed of the ports on your motherboard. However, that
would conflict with my message from XP, in that I get the message you've
gotten when I plug a USB 2.0 device into a USB 1.1 port, and you MIGHT
be getting it when you plug in a USB 2 hub into full speed USB 2.0
ports. So, in the end I haven't anything else to offer, but it's 4:15am
and I'm off to bed :-)

PS- Do we know each other? I met a Robert Nicholson in Australia who has
since moved to the UK.

My spare PC has a 7VAXP in it, and didn't need any additional drivers
for the USB 2 support to work properly in SP2.
It is normal of course, for XP to show both USB1.1 and USB2 root hubs
being present.

Not sure what is going on for you, but I remember several USB 2 related
problems with this board being ranted about in the Gigabyte forums...

Mine's running the "lumberjacker" bios (mainly for the hacked full
Promise support), in case the bios revision makes any difference.

Have you tried Device Manager>Universal Serial Bus Controller>Standard
Enhanced Pci to USB Host Controller>Update Driver>Install Software
Automatically. Driver should be usbehci.sys
 
Simple fix. USB 2.0 is there, but not enabled. WinXP
does that a lot. Go to My Computer ... properties ...
hardware. In the hardware list, you will fine USB ports.
Sometimes theres a ! mark or it is colored as if there
is a problem. Anyway, Rclick and tell it to update the
drivers. It will do its thing and exit, and USB 2.0 will
be enabled. Brilliant, Huh!

Actually, I suspect they are both present on the motherboard. The BIOS
boot-up screen shows 3 x USB 1.1 and 1 x USB 2.0. I'm going to reboot and
have a furtle in the BIOS.

It doesn't seem to matter which of the six ports I plug it into.

One thing I did noticed on boot-up was the device status screen just before
it launches Windows XP. I didn't have time to study it in detail but it'd
listed a number (probably 3) USB 1.1 devices and a single USB 2.0 device.
Now either the board has four USB root hubs (3 x 1.1 and 1 x 2.0) or some
jiggery pokery is going on to connect 3 x USB 1.1 root hubs through one 2.0
root hub. They are still USB 1.1 though.

Okay, checked out the BIOS screen at boot-up. There are 3 x USB 1.1 root
hubs and 1 x USB 2.0 reported on the startup screen. But there are only six
USB connectors in total off the motherboard: four in 2 x 2 connectors on the
motherboard and 2 directly off the motherboard through the back panel.

And they all appear to be USB 1.1, well at least according to Windows XP.

So the mystery is "Where does the USB 2.0 root hub present itself to the
real world?" :-)

Could any of the cables on the 4 heares be reversed.

Sorry for the typo, I meant headers.

Your board has 3 USB 2.0 ports. Have you installed VIA 4 in 1Driver? Will
have been on CD supplied but is also updated on internet, just google 'VIA 4
in 1'
