THis is the file.

You can try the download page, and see if you end up with
the same thing or not.

Here's a picture of what I see on the previous page.
I selected the top link for my test.

- Go to www.microsoft.com/download.
- Search on "exfat". No many matches show up (I only got 4).
- The first one in the list is for KB955707.
- Short description is "Install this update to add support for the exFAT
file system format."

BeeJ was thinking very hard :

Turns out that Firefox was the problem. No button!

I tried Chrome and the button was there so I downloaed and installed.

Now my Win XP Pro can read/write the exFat pen drives perfectly.

Now how about USB3 speed support? The PC has USB3 ports.

To prevent problems with Firefox later, have you tried loading Firefox
in its safe mode to eliminate that add-ons are causing a problem with
rendering a page? You might have adblock software that is altering the
content of the page. There's a Greasemonkey add-on that specifically is
to modify the code in the received page to alter how it displays. Get
the add-ons out of the way to see if Firefox itself has a problem
displaying web pages by Microsoft.

Probably should start another thread on that topic instead of mixing it
in here as a subthread.

Have you yet checked the so-far-unidentified mobo (if you buy parts to
build your own) or the PC maker's web site (if you buy pre-builts) for
WinXP USB3 drivers? If it's a recent mobo or PC, there's a good chance
its maker doesn't provide any support for Windows XP.

[Paul]

You're in a WinXP group, so the drivers are chip specific.

If you have an Asmedia USB3 chip, you'd use an Asmedia driver.
If the card came from Startech, Startech would have your
Asmedia driver. Or, perhaps Asmedia would have a new one.

Check the card or motherboard company first, then check
the USB3 chip maker site next, then drop back here if nothing
is available.

If you bought a high end USB3 flash key, then you might
have reason to be excited. But for the rest of us that
bought a $20 USB3 key, the performance is not dramatically
different. In some cases, there is a fair difference between
read and write speed (write should be slower).

When it comes to buying USB3 flash keys, *do not* buy a key
with a plastic barrel. Only buy ones with metal barrels.
The metal barrel is dimensionally stable, helps the pins
and contact mate properly (proper connector capture), so
none of the pins get busted off on the USB3 key. I have
a plastic USB3 here, where one pin is busted off, and now
it runs at USB2 rates :-( The pin is too tiny to solder.

If, someday, you want to connect an SSD to the USB3 port,
read this article first.

USB3 has plenty of bottlenecks, so your experience can be
different from the guy next door. For example, the very first
entry here, happens when the owner of a ten year old
computer, attempts to put USB3 into the computer. The
PCI bus is a definite limitation, for the 33MHz 32 bit flavor.

USB3 bridged card with PCI connector - 100MB/sec typical max
USB3 PCI Express card plugged to PCI Express 1.1 mobo - 200MB/sec
USB3 PCI Express card plugged to PCI Express 2 mobo - better
USB3 port on Intel or AMD Southbridge of the mobo - best (system bus is not
a bottleneck)

USB3 disk enclosure - 200MB/sec typical
USB3 enclosure or dock with UASP - much better
(USB3 flash stick) - stated on box
BlackMagic HDMI capture device, tray format, USB3 - several hundred MB/sec,
only the "best" USB3 works

When connecting, pick the lower of the values from the two groups
of entries. You have a computer with one of the first four
connection methods. And the external device is in the second
group. For example, a USB3 bridged card with 100MB/sec limit,
will give a "failure" message in the Blackmagic software, as
soon as the software attempts to benchmark the transfer speed.
They test for sufficient transfer speed, to prove the
device will not drop frames during capture.

Other examples, like storage combos, are more forgiving.
A super-fast enclosure, plus the crappy 100MB/sec
USB3 card, equals 100MB/sec speeds. The transfers still work,
the hardware does not complain. Only the user is a bit grumpy :-)

re: exFat

I'm not sure if that MS download is available anymore, but even if you find
it, I wonder if it's worth it? I have it, and haven't ever used it, due to
its lack of widespread use on many devices or systems. It just seems safer
(to me) to stick with FAT32 or NTFS, but YMMV.

[BeeJ]

This is an MSI MB A75MA-G55 and I have downladed and installed all MSI
drivers for both XP and Win 7. (Dual boot)

I got the exFat driver from MS. Installed and working.

This MB has USB3 ports but not sure if XP will support that speed.

Yes I have had a bad experience with a plastic the connector on USB3
pen. it is going back to store. the USB3 pens I am now using are all
metal connectors and work perfectly wherever I plug them in.

On a Win 7 USB MB PC i do get very high read & write rates. It works.

[Paul]

WinXP does support that speed. The USB3 driver installed, it
can install a running monitor task. The monitor task will say
"this device could work faster in the USB3 port", if
you plug your USB3 device into a USB2 port, *and* the USB3
driver is present. Without the USB3 driver present, you
won't see that notification box pop up.

*******

The manual for your board, says it has A75 chipset ("Hudson D3").

http://dl.msi.com/download_files/mnu_exe/E7696v1.1.zip

The article here, says the Southbridge has four USB3 ports built-in.
AMD got some IP from another USB3 company - it's my understanding
they didn't build the USB3 port on that chip from scratch. And built-in
ports are the best, in terms of performance. Because the bus connection
to the USB3 logic block, isn't a bottleneck.

http://en.wikipedia.org/wiki/Comparison_of_AMD_chipsets#Fusion_Controller_Hub_.28FCH.29

"USB 3.0+2.0+1.1 == 4 + 10 + 2"

The manual is a bit screwy, in that the spec section up front in
the manual, doesn't tell you that JUSB3, the 20 pin internal header,
is a dual connector. It takes 9 pins to do a set of USB3 wires,
so the 20 pin connector is sufficient for two circuits. That
makes two separate USB3 ports on the back, and a dual header
carries the remaining two USB3 ports when you need them.

*******

The driver is apparently not made separate, so USB3 for A75 gets
covered off when you install the huge chipset driver package instead.

Hmm ... don't think I see it but maybe i am in the wrong port.

Win XP SP3 with USB exfat installed. do i need specific USB3 drivers?

the front ports are black and there are blue rear ports so in dual boot
to Win 7 i see fastness on the blue. rear are directly on mb but fron
are on cables and box may not have the right color connector.
box is Sentey compact desktop. (noisy fan model. lol)

my pen drive are all USB3.

Win XP Pro SP3 (all updates from MS ) does not popup a USB2 port using
a USB3 pen so maybe wrong or miussing USB3 drivers.
How to tell?

The MB is MSI A75MA-G55 and all MSI driver are installed.
I think, because there update utility keeps saying the net drivers need
updating but never allow it. so i went to website and downloaded all
there and installed ok but ther app version 6 (latest) still says net
drtiver out of dare. Hmmm.. but that should not affet USB.

That chipset driver you mention from MSI is the one I used and was
watching as it did the usb driver install along with a bunch of other
stuff. all went ok but all above is still what it is. I'll fiddle a
little more. all seems good enough for now.

[Paul]

Make sure USB3 is turned on in the BIOS, before
doing the chipset install. Just in case the installer
needs to see the USB3 enabled, before installing
amdhub30.inf and amdxhc.inf.

You should see entries in Device Manager for the
USB3 block. The two INF files will have all the
details, as to what ID strings will be put in
Device Manager (look near the bottom of the INF files),
as well as what code files were installed to make it work.

The front panel of your computer case, is probably
fitted with USB2 (black) ports. The wiring inside
the case would consist of a 2x5, suited for a 2x5 USB2
header on the motherboard.

A different wiring harness and assembly would be needed
for powder blue USB3 ports on the front of the case,
including a wiring harness with 2x10 connector on the end.

If the rear powder blue ports are giving you the expected
speed, then the drivers are indeed installed. You can use
the free version of HDTune (hdtune.com) to do a read-only
benchmark test on the USB3 pen drive, while it's plugged into
the USB3 port. As long as more than 35MB/sec is seen, it is
working as expected. My first USB3 stick, would only
do 45MB/sec, but that was sufficient to prove my driver
was working. Just barely. The second USB3 stick, did maybe
70MB/sec, before I broke a pin on it.

Probably correct about the harness. I might opt to upgrade that but I
am in a remote location now and it is not possible until next week.

I'll run a front vs back speed test too.

Thanks!
