Hi
I have a MSI KT3-Ultra ARU motherboard equipped with 2 USB1.1 ports and 2
USB 2.0 ports. The USB 2.0 ports are supported by NEC uPD720100 chip which
is EHCI (Rev .95) compliant. I understand that this was NEC's first attempt
at USB 2.0 chip. When I attempt to use my portable USB 2.5" HOT DRIVE
(which is USB 2.0) on the USB 2.0 ports I get the following error:
"Hi-speed USB device plugged into non-hi-speed USB hub". I am running WinXP
Pro with SP-1 installed.
Before I get into more details on the failing scenario I want to let you
know what I did to determine that all the hardware (motherboard, cables, Hot
Drive) is not faulty. I have set up very simple test system as follows:
1.. MSI KT3-Ultra ARU mother board equipped with USB 1.1 and USB 2.0 ports
(4 of each)
2.. -equiped with VIA KT333, VIA VT 8233A and NEC uPD720100 chipsets
3.. AMD 2.5 Gig Barton CPU
4.. Crucial 256Meg Ram PC2700
5.. Maxtor Millennium G400 4X AGP video card
6.. Maxtor 40 Gig Hard drive
7.. D-link DFE 530TX NIC card
I installed WIN 98SE and drivers from CD-ROM supplied by MSI. These included
AC97 sound, VIA 4 in 1 and USB 2.0 for the NEC UPD720100 chip. Along with
that I installed the required video driver, NIC card and USB HOT DRIVE
drivers. I connected in my HOT DRIVE into the USB 2.0 ports and VOILA, I
have a high speed USB connection. My 650Meg test file transfers in about 65
sec. If I use the USB 1.1 ports the same file takes about 14 min to
transfer. This definitely proves that all my hardware is not faulty as I
have USB 2.0 speeds with WIN98SE drivers provided on the MSI CD.
Now for the problem: I have set up exactly the same hardware except now I
installed Win XP Pro with SP1 update. The USB 2.0 driver is apparently
provided by Microsoft through SP1 update as no driver is supplied by MSI for
WIN XP. When I connect my HOT DRIVE to the USB 2.0 ports I get the
following: "Hi-speed USB device plugged into non-hi-speed USB hub". I know
it's running at USB 1.1 because the 650Meg test file takes about 14 min to
transfer. When I connect to USB 1.1 ports, this error message is not
output, however the test file transfer takes about 14 minutes due to lower
USB 1.1 speed.
The USB configuration from Win XP Device Manager is as follows:
NEC PCI to USB Enhanced Host Controller (B1)
NEC PCI to USB Open Host Controller
NEC PCI to USB Open Host Controller
USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
USB Root Hub
VIA REV 5 or later USB Universal Controller
VIA REV 5 or later USB Universal Controller
From what I have read so far this configuration seems to be correct. I have
read a few Microsoft knowledge articles and performed the suggested
workarounds:
-updating the USB 2.0 driver after SP1 application
-checking USB 2.0 driver file details,
-their base line is: 29-Aug 2002 5.1.2600.1106
-mine are: 03-Jul 2003 5.1 2600.1243
I even had MSI replace the motherboard for me in the hope of getting a
KT3-Ultra 2R (I also have one of these, works great) in return, but no, I
got the same model back as a replacement with the same problem.
Searching the Web and news groups I have found many, many posts with exact
same problem but no solutions. If any one has a hint or suggestion I would
really appreciate your input.
There are however, a couple of questions that I have that could lead to some
answers.
1. Does the Win XP SP-1 USB 2.0 driver support EHCI (Rev .95) chipsets?
Nec has the following USB 2.0 chips uPD720100A EHCI Rev.95 and uPD720101
EHCI 1.0
My motherboard has the first one and if support for EHCI Rev.95 is not
there, then I am shafted and I will go after MSI for a motherboard upgrade.
2. Does the VIA VT8233A chip have any issues or requires drivers for USB
2.0?
Thank you for any and all input.
