Repost: A7v333 and USB 2.0 problem
Henry LaMuth
answers my question below.
I have XP Home SP1 installed and the jumper is enabled for usb 2.0. A
usb 1.1 device is active on all 4 usb ports, but I don't see any
indications in device manager....except one....for an advanced
controller and certainly nothing about usb 2.0 under device
manager/Universal Serial Bus Controller: VIA USB Enhanced Host
Controller is the only entry out of ten that would seem to indicate
usb 2.0 support.
Additional information is that I am using Bios Rev 1014, system is
very stable, and I don't have a USB 2.0 device yet. I am not sure the
bios is relevant, but not having a USB 2.0 device seems to be a
problem....which I want to solve before investing at this point, since
I am not inclined to get a new mother board...but maybe an multi-port
card if I must. So, here goes, again.
So, how do I find out if I have a bad board or jumper...since I don't
have any usb 2.0 devices yet? I have swapped jumpers in case the ASUS
jumper was bad....and at this point I have had the board long enough I
will have to live with it if it is bad...but how do I know it is bad?
One urban legend I have heard is that the usb 2 drivers don't load
until a usb 2 device is attached to the usb 2 ports. True or not?
Thanks for the help.

universal host controller and the VIA USB Enhanced Host controller which is
the only reference to USB2 I am running sony DRX500UL DVD writer a logitech
usb 2camera and a canon usb2 scanner through a powered hub from the ports it
sounds like yours is functional. it is far simpler to test if it is
functional with a USB 2 device bios is no problem mine worked from Bios 1005
and is still on 1017 can't answer your other points for sure it was too long
ago when I installed I am using a corporate XP sp1a and the drivers were
there from the word go as I created a slipstreamed version of XP

2.0 drivers separately, if your board supports it. Mine is the first
listing under the Universal Serial Bus controllers in Device Manager, but
mine is Intel and it states "USB 2.0 Enhanced."

Without the usb 2.0 references in Device Manager, is it possible that
your 2.0 device is only operating at 1.1...and you just don't know it?
I am not sure what XP tells you when you put a 2.0 device on a 1.1
port...since it should work...or should it? That is, what are the
messages that you might get if you swapped usb 1.1 and 2.0 devices
among 1.1 and 2.0 ports? If I put a 1.1 device on a 2.0 port, what
happens...and visa versa: a 2.0 device on a 1.1 port?
Henry
Henry LaMuth
Maybe that's the issue. How do you load usb 2.0 drivers, since they
seem to be embedded or hidden within xp? Like I said, I have a 1.1
device that is equally active or responsive on any of my four
ports...so when and how are 2.0 drivers loaded, or how do I load them?
Henry

They may also come with a device, or maybe on the asus site or microsoft, or
whoever makes your chipset.

The USB 2.0 drivers come with XP SP1 but they are not "loadable" in
the sence of having a specific location to find the drivers and a
specific location to install them. You have to have a device installed
first to install the drivers...that's what's missing: a USB 2.0 device
and that is the whole issue: how do I get my two USB 2.0 ports to be
recognized by XP? Or, if they are, how do I get the Device Manager to
reflect that these are USB 2 ports and that they are installed and
working?
Or is the fact they are not already installed mean mine are bad or, as
urban legend has it, they won't install until I put a real USB 2
device on those ports? Questions questions questions but no answers.
In XP add hardware, the wizard wants real hardware connected to
install it: no USB2 hardware, no installation. It seems like that may
be the issue. Can anyone confirm that until I actually put a USB2
device on the ports, the drivers will not be installed and the Device
Manager will not show active usb 2 ports?

Henry - There are two parts to USB device installation. The chipset
needs drivers, in order for the chipset to offer USB "services" to
the OS. This is like any other part of the chipset, like the IDE
interfaces for your disk drives. Even if you have no USB devices
connected, Windows should discover "new hardware" in the form of
the USB controller and the USB root hub inside the chipset.
Some people have trouble with this, and perhaps the reason has to
do with the install order. If you install WinXP, it doesn't have
support for USB2. Next you install SP1, which does have support.
But, for whatever reason, sometimes Windows doesn't recognize the
USB2 devices inside the chipset, after SP1 is added. The solution
that works for these people seems to be - going into safe mode,
deleting the USB controller and root hub in the Device Manager,
and letting Windows discover them again on the next reboot. Since,
at this point, the system is at SP1 level, it should properly
recognize both the USB 1.1 and USB 2.0 controllers that both live
inside the chipset.
The other part of USB devices, is hardware specific drivers for the
things you plug in. Some of these will already be shipped with WinXP
or in SP1, and so there is nothing to do. If you have some kind of
weird device, you may have to install drivers, to map the plugin
device into some interface that Windows understands. With some
hardware, the instructions are to install drivers BEFORE plugging
in the device (like maybe a scanner). Other hardware allows
installation when Windows "discovers new hardware". The
instructions with the individual products will tell you which
is appropriate. Notice that in the BEFORE case, there is no
hardware that Windows can see, and yet the driver can be installed
and registry entries made, so that the OS is ready when the device
is eventually plugged in.

Now, to some specifics. The A7V333 chipset only has USB 1.1 on the
Southbridge. So, Asus added a VT6202 PCI attached device on the
motherboard, to give you some USB2 ports. The VT6202 will show up
as new hardware, if the jumper on the motherboard is set to enable
the chip.
In terms of drivers, I see three packages. These packages appear
to be Orangeware (rather than Microsoft), and in one case, are for
WinXP and Win2K, as well as the normally unsupported OSes like
Win98se and WinME.
ftp://ftp.asus.com.tw/pub/ASUS/mb/socka/kt333/a7v333/
a7v333 usb2.0.zip 1,651K Mar 27, 2002
(This one contains the tiny 42KB OUSB2HUB.SYS and 30KB OUSBEHCI.SYS
characteristic of an Orangeware stub driver. Will be installed for
any Microsoft OS. Presumably this package was released before SP1
came out.)
ftp://ftp.asus.com.tw/pub/ASUS/mb/socka/kt333/a7v333/
VIA_USB2_Driver Package_V225M.ZIP 13,004K Jun 7, 2002
Multilanguage. Contains a Microsoft WinXP USB2 driver plus QFE 312370,
a hotfix issued before there was SP1. The ReleaseNote file also
mentions you can edit a .ini, and get the Orangeware driver to
install instead. This Orangeware supports VT6202 and VT8235.
I don't recommend the Microsoft option if you have installed SP1
or are planning on installing SP1. You could try the Orangeware
from this package if you are otherwise having trouble (like
WinXP SP1 doesn't work or Windows Update doesn't help you).
ftp://ftp.asus.com.tw/pub/ASUS/misc/usb20/
VIAUSB2V242L-M.zip 13,074K Oct 7, 2002
Multilanguage. This package no longer has a Microsoft WinXP/Win2K
option, instead it takes you to Windows Update. There is still
Orangeware for Win98SE and WinME. I got this info from the
ReleaseNote file inside the ZIP.
So, if you have SP1 loaded or are planning to, visit Windows Update
and see if anything is available for the VT6202. If you try this and
it doesn't work, you could try the 225 package, and edit the .ini
file according to the instructions, so that the OrangeWare stub
files are installed.
If it still doesn't work, your VT6202 could be defective, or you
haven't installed the jumper that enables the VT6202.

Paul, great info and advice. I was just over on the MS XP forum and
got nothing but grief and garbage. I appreciate your giving me
something to work with. My dilema is that I don't know if the jumper
is bad...it is set for usb2...and I don't know what the XP Device
manager should show if the USB controllers are installed and active. I
know the ports are all usb 1.1 active, but not having a USB 2 device
to put on the 2.0 port, I cannot test the throughput. What should the
via chipset entry in USB controllers be in the xp device manager? I
have a single entry for an advanced controller and nine others that
look "plain vanilla". Like Dylan sang...or the opposite of what he
sang, I need a weatherman to know which way the wind is blowing.
Thanks for a great post.

I downloaded the via file you identified and went into device manager
and universal bus controller. It let me change the enhanced driver
using the location of the XP usb2 driver from the file. None of the
others would let me do that....they support the usb 1.1 ports,
apparently.
So, for the first time something in Hardware Manager actually says usb
2.0. Seems pretty kludgy to me. Nothing on the MS site addresses
specifically the VT6202 device and drivers....neither Asus nor via is
in the list of manufacturers for usb hubs, etc....or under
Motherboards, either.
I have ten entries but only one says usb2. Is this normal? Again,
pretty cryptic. However, I am not sure this actually tells me the usb2
ports support usb2 devices...or does it?
Thanks, again for you advice.

Generally, what this means, is there is one controller logic block and
it is used to drive multiple PHY interfaces. With a 60MB/sec max transfer
rate, you couldn't have too many of these controllers before the PCI bus
would be flooded.
You won't know whether it really works until you try it :-)

(First: "Enhanced" in USB context seems to equal "USB 2.x")
Onboard the A7V333 is a Southbridge chip, VT8233A, from VIA that
includes 4 USB 1.x Controllers (4 "VIA rev 5 ..." entries in the Device
Manager (DM)). Each controller contains an USB Hub (4 more entries in
the DM). Each of these Hubs support 2 USB Ports.
Also onboard the A7V333 is a USB 2.x chip, VT6202, also from VIA and it
contains (or is) 1 Controller (The Enhanced entry in the DM), and inside
it is one Hub (the tenth entry in the DM). This Hub is a little
different in that it can drive 4 ports, as you can see under the Power
tab. It all becomes esier to see if you sort your DM by Devices.
What's a little curious though, is that you can only get a total of 8
USB ports from the A7V333, not 12 like you would assume from the above.
It seems the USB 2.x chip not only adds 4 ports but also eats up 4 of
the southbridges 1.1 ports. So i agree things look a bit confusing.
Also if you look inside USBPort.inf you'll see that both USB 1.x and 2.x
Hubs are named the same. (Maybe there is no difference in the Hub-part,
between USB 1.x and 2.x ... I don't know.) So if i interpret things
right both you and i have things looking correctly in the DM. Probably
the drivers got installed correctly after you installed Service Pack 1
without you noticing the change.
"Now you're probably wondering by now - just what this ... is all about.
What's probably got you baffled more - is what this thing here is for.
It's nothing - It's something i learned over in England."
