For USB2, I believe the minimum requirement is WinXP SP1 and
Win2K SP3.

I expect you need to install SP3 or SP4 for this to work.

Thanks for the URL´s, I will try this tomorrow.
Because I´m using XP, SP2 is actually the highest SP.

Application Note
nForce2 MCP-T/MCP
USB 1.1 Device Compatibility

DA-00822-001_v01 2
04/08/03 NVIDIA CONFIDENTIAL

USB Device Compatibility
This application note addresses the compatibility of the NVIDIA®
nForce™ MCP and the nForce2 MCP-T and MCP processors with several USB
devices in the marketplace. The devices listed below exhibit similar
USB non-compliance.

• Aztech UM9100-U USB modem
• Creative Nomad Muvo MP3 player
• Creative Nomad Jukebox Zen MP3 player
• SCM video capture device (DCS200)
• Sonic Blue Rio S30/35/50 MP3 players
• St. Johns Technology USB2 HDD
• NuSLIM SUB 2.0 Portable HDD

Detailed Description
Customers have reported that several USB devices do not function
reliably with the NVIDIA MCP processors. NVIDIA has tested them and
determined they have very large clock jitter and fail the USB1.1 eye
diagram requirements. Placing any of these devices behind a USB1.1 hub
does not resolve this issue since the hub will not reclock, but will
pass the jitter to the MCP. Depending upon the chip used in the USB
device, a workaround or fix may be available.

Proposed Solutions
Several solutions exist depending upon the specific device.

General Solution
These devices work with MCP/MCP-T if they are behind a USB2.0 hub.
Since the USB2.0 hub reclocks, the jitter is not passed through to the
MCP/MCP-T. This is a general solution for all devices mentioned in
this document.

Sigmatel-Based Devices
Devices that use the Sigmatel STMP3410 part work effectively if a
firmware update is applied. (Please see the respective websites for
updated firmware.)
These devices include:

• Creative Nomad MuVo MP3 player
• Creative Nomad Zen MP3 player
• Sonic Blue Rio S30/35/50 MP3 player

Note: These devices need to be updated in a non-nForce2 based system
or there may be device failures while flashing.

Genesys-Based Devices
Devices that use Genesys GL811 chips may exhibit a failure if a large
file is copied. When a file (usually larger than 20 MB) is copied to
the USB drive, an error is prompted during the copy transfer. This
causes the drive to disappear from the system device manager. Versions
20 and beyond are compatible and will not exhibit this failure.
These devices include:

• St. John's Technology USB2 HDD
• NuSLIM SUB 2.0 Portable HDD

http://www.epox.de/_boarddetail/8rda+/nForce2_MCP-T_MCP...

http://www.elito-epox.com/_boarddetail/8rda+/nForce2_MC...

Final solution appears to be purchase and install a "PCI USB cards
cheaper and garunteed rather than being a try this solution" per
posting by 'wonkanoby' at above forum


I'm still fighting a SanDisk Imagemate SDDR-89 USB 2.0 12-in-1 card
reader. It won't work with my Windows 2000 SP4/5 A7N8X-E Deluxe 2.0
with BIOS V.1008. Won't work means the four green lights don't turn on
and the four extra drives letters don't appear in "Control Panel".
However, it works fine with W98SE and USB 2.0 PCI card with factory
driver from 1.0 version CD. I can get several other USB 2.0 devices to
work off any of the six USB ports - two of which I have extended to
the front of the chassis.

Found another refrence at
http://www.techspot.com/vb/printthread.php?t=7934&page=...
to NEC USB 2.0 driver at
http://www.techspot.com/redir?target=ftp://ftp.abit.com...

They show up in Device Manager _BUT_ still same problems.

Guess I'll go by a real PCI USB 2.0 card and say forget it :-(

The jitter problem was announced a while back. If you already own
a USB 2.0 hub, then using the hub to clean up jitter is a good
test. If you don't own a hub, then buying a PCI USB2.0 card is
definitely the right answer. The advantage of the PCI card, is
if the problem is really a driver problem or a BIOS problem, the
symptoms might change with the use of the PCI card. The jitter
problem only applies to a limited number of external device
designs. I expect Nvidia has learned how to design a USB
interface since then.

Did you try this ?

Paul:

Yes, I took your previous advice on following USBman remove stuff in
SAFE MODE and that didn't solve the problem either?


I have added the NEC drivers previous referenced. Thus I have six USB
items in Device Manager. Each time install SanDisk Imagemate SDDR-89
USB 2.0 12-in-1 card reader - nothing recognizes the device.


I also sent question to ASUS tech support and referenced this forum.
We shall see if they answer?


No, I have not yet added a PCI USB 2.0 card.
Does anyone have a brand/model to recommend?


General thoughts:
I expect for next mobo choices we'll investigate more fully some of
the things learned during past year of building a dozen systems based
on three mobo brands :-)

IMO discussion lists/forums are clearly more informative than
website/magazine "reviews". Which are often simply rewrites of a
manufacturers press release. Or at best a brief build and running a
few generic middle of the road devices and a few middle of the road
benchmark utilities.

Thanks in advance to everyone,

There are other people with USB problems on the A7N8X.

http://www.nforcershq.com/forum/viewtopic.php?t=27104&h...

The best info, seems to be on the private forums. At least when
there is a recognized problem, you get more feedback from people
with the problem.

In terms of USB cards, it would take a lot of Google searches
to build a consensus on which cards are good or bad. It is probably
easier for you to locate a product, and them type the model
number into Google, and see if there are any known problems with it.

As for review sites, they cannot possibly test enough other products
with a motherboard, to find problems like the Nvidia jitter problem.
The only way to detect such problems, is to wait many months before
buying a new product. When a product is mature, much more is known
about its shortcomings.

Paul:

Another thank you for your excellent research.

Appears the better solution is add a USB 2.0 hub. I found consistently
positive reviews on the "Targus (PAUH212U) 7-Port USB 2.0 Hub".

Has anyone had any experiences with this brand/model of USB 2.0 Hub on
their A7N8X mobo?

As previously mentioned I'm using Windows 2000 PRO with SP 4 and all
updates thru the Feb. 2005 releases from Micro$oft. All of which I
deleted during testing of the USB problems and reinstalled.

Also fired up on table the second A7N8X-E Deluxe Rev. 2.0 motoheroard
from out of box and moved everything over to it. I only found the
problem with SanDisk Imagemate SDDR-89 USB 2.0 12-in-1 card reader.
The other USB 2.0 devices I own work fine. Thus same results.

So if you follow back up this thread you'll see there is an admitted
fundamental 'jitter problem' in the USB ports with the combo of this
motherboard and chipset implementation which now appears to be
consistent on the two A7N8X-E Deluxe Rev. 2.0 we own.

Check out this article
http://www.techspot.com/vb/printthread.php?t=7934&page=...
written 09-27-2003 and you'll see " a list of devices known to have
problems with this board :
* 6in1 Internal Reader 3 1/2 usb1, Flash card reader card X4-USB
* MP3 Player DAP 128 Mb (Additek)
* PNY 6in1 Player ( metallic grey look ) which doesn't even work on
the a7n266-e
* Creative Muvo 128Mb ( Solution : flash with new firmware update,
instructions contained in ReadMe file )
* The Archos JukeBox 20
* Compact Flash USB HAMA Player
* CF USB Player from Crucial"

The troubleshooting techniques mentioned in the above article are same
as 'Paul' suggested. Which have not cleared up the problem on my two
mobos.
Thus I'm back to the options of testing a PCI USB 2.0 card and a hub -
probably "Targus (PAUH212U) 7-Port USB 2.0 Hub".

Both of which will wait until later in the month when I have time to
play with techy testing.
