One other suggestion.Try installing the manufacturers chipset
drivers,from your install disk, rather than the (supposedly latter)
version that Microsoft installs if you download updates.
I have recently seen a whole 'crop' of machines showing USB problems.
Not recognising drives, data loss, errors being reported, etc. etc..
All hae been based on the Intel P35 chipset, and all had recent MS
updates. Putting the older chipset drivers in (seems to be anything
older than about December last year), has got the USB working properly
again...

Possible but I doubt it because the chipset drivers have notjhing to do
with USB. Microsoft provides the USB drivers on XP and Vista for most
chipsets. P35 mb's have no specific newer drivers for USB.

With the 965/975 chipset, Intel drivers are required for proper USB
function. It's probably the same with the P35 chipset. The BIOS
provides legacy support so the OS can be installed, then the Intel
chipset driver (the first thing that should be installed after the OS)
provides full USB functionality (in addition to many other device
functions).

I had a similar issue with my new M3A. Turned out to be a setting in
the BIOS regards IRQ handling. The default was "Hardware controlled".
I switched this to "OS controlled" (That is, let "Windows controll
IRQ settings" and that solved the problem for me.

I had a similar issue on my new M3A motherboard in that it would not
recognize a camera's memory card in a thumb drive. I really don't know
what I am talking about---just a novice---but I did get the problem
fixed pretty easily. I noticed that the error message that popped up
after the thumb drive would hang was that there was an I/O error.
This got me looking into I/O stuff and I started looking at IRQ
assignments to see if this could be causing some of the problem.

I went into the BIOS and noticed that the default setting on IRQ
interrupts was set to "hardware controlled". I figured maybe the
motherboard was having problems handling all those USB ports (I hooked
them all up, have not only the 6 on the back plane (obviously) but I
hooked up extension cables to the interior headers (four more USB
channels) and routed them to front panel USB ports. My camera thumb
drive worked on the 6 back plane USB ports---but was unrecognised by
the front panel ones. This is what got me thinking that maybe the
default settings were set up for the USB ports on the back plane--but
not the extra ports on the motherboard since probably not too many
people use them.

Anyway---what I did was go into the BIOS file and change the default
IRQ handling scheme from "hardware controlled" to "Operating System
controlled". That is, I changed that setting to let Windows XP
handle the setting of IRQ interrupts. My thought was that when
Windows booted---it would recognise those extra USB ports and assign
IRQ settings that would prevent those I/O errors. So I made the
change, saved the BIOS settings, re-booted into the OS and viola---now
my front panel USB ports are working just fine. The OS recognises the
added ports, even is able to read what device is hooked to the front
panel ports, etc.

Now---as I said--just a novice and I really don't know what I am
talking about---all I know is what I did and that my thumb drive (that
like you said--worked on other computers I have (about 4 of them plus
the wife's laptop) and on my back panel USB ports) now works just fine
now that Windows is controlling the IRQ assignments. Maybe---Just
Maybe, this is what could be happening to you??

Sorry---faulty memory. I had done that troubleshooting weeks ago.
I just went into my BIOS again and rechecked what I did. It was two
things. You might want to try them and see if it fixes your issue.

1) Enter BIOS set up and tab over to "Advanced"
THen under the sub-tab "PCI PnP"
Then under that sub-tab "Plug and Play O/S"
The default setting was "No"
So it was letting the hardware control the PCI slots---and as I
understand it, was only bringing up those PCI slots and IRQs necessary
to boot the machine to the OS.
I changed this setting to "Plug and Play O/S" to "Yes"

2) Same BIOS tab of "Advanced"
THen under the sub-tab "USB Configuration"
Then under the sub-tab "Legacy USB support"
I changed the default setting of "2.0" to "Auto" (you can also set
it to "legacy", but I didn't want to limit all USB ports to USB 1.0
speed. I figured "Auto" setting would let the USB controller query
the device attached and if Version 1.0 device--set that speed, if
Version 2.0, etc.

Anyway, saved settings and booted into OS and then everything worked.
So I think it may have been one of the things above. Or not---as I
said, I am just a novice and really don't know what I am talking
about. Just know my Front Panel USB ports are working fine now with
no I/O errors and recognizing my thumb drives, cameras, scanner,
external USB hard drive, etc--when they didn't work before I made
those two BIOS setting changes.

So I hope that helps.

OK, I'll look into what chipset drivers are installed and see if there
is an updated version. Thanks.

It's possible but I think I already have it set to let the OS handle IRQ
assignment. I will check later though. Thanks.
