HI-SPEED USB Device Plugged into non-HI-SPEED USB Hub

[DmsTech]

Hi
The case, USB cables or modules are not the problem. Using Win98SE and the
USB 2.0 driver provided by MSI, I tested all 8 USB ports succesfully, 4-USB
1.1 and 4-USB 2.0, I am using the same case, cables, etc, and can switch
between WIN98SE and WinXP with SP1 by using Norton Ghost. Bottom line:
Win98SE all 4 USB 2.0 ports run at high speed and under WINXP they run at
USB 1.1 speed. I am convinced it's WinXP driver issue more tham ever.
There are way to many posts all over the net/ngs for this to be a harware
issue of any kind.
Thanks for the replay

Hi Ted, I have an MSI KT3 Ultra as well, and had a similar problem. If

you are trying to hookup to the front USB connectors rather than the back it
may be your case. I have an Antec case which would only support USB 1.1, I
was able to e-mail them and they sent me a replacement module for my case
and now USB 2.0 works great. Hope that is your porblem too. Contact your
case manufacturer they may be able to help if that is the case.

Did you check device manager?

Hi
Many times, over and over and over.............
Just look at my previously posted info to see what I have done.

Have you resolved this one yet?

I have exactly the same problem and just seem to find the same answers - your plugging it in the wrong port or something equally useless! I have an ASUS P4B533-VM which supports USB 2 using Intel 82801DB USB controller. I have 4 ports physically on the motherboard and another port for connecting to the case (provides additional two ports on the case). ALL PORTS support USB 1.1 and 2.0. Device manager shows 3 USB Universal Host Controllers with a USB Root Hub for each (providing 2 ports each) and then a USB 2.0 Enhanced Host Controller with a USB Root Hub (providing 6 ports). I have tried BIOS updates, driver updates, BIOS reconfiguration, uninstalling reinstalling drivers and so on and on and on, but cannot get a high speed connection. When ever I plug in my hard drive it always connects to a USB 1.1 root hub and not the root hub for the USB 2.0 controller. Like you there is no physically seperate port for USB 2.0 so I cannot simply plug it in somewhere else.

I also have a Tablet PC with USB 2.0 based on the NEC chipset as yours is and this works fine!! Both PC's are XP with SP1 and both are using baseline drivers of 5.1.2600.0 currently, not the updated drivers you have, although I have tried the updated drivers and it made no difference. Apart from the chipset differences the only other difference is the enhanced controller on the Tablet PC is allowed to use 12% of bandwidth where as my PC controller can only use 10%.

Hi
I have an update but unfortunately it's not a solution to the root cause of
this problem. MSI support could not help me, or most likely does not want to
admit that they have a problem, finally descided to RMA the board and
replace it with a KT3 Ultra2R. It took many e-mails to finally get them to
do this..This board has a VIA USB2.0 chipset and the drivers do work
correctly to provide USB 2.0 speeds. I have one of these boards already.
Regards to all.

Update:

I logged a call with ASUS on my problem and after several rather useless
suggestions gave up with them and started looking closely at my motherboard
settings. There were no jumper settings to help but there were several BIOS
settings to try. After many attempts it finally came down to a setting call
"USB 2.0 Reference Voltage". On my board it was set to "Maximum" and there
are three other choices "Low", "Medium" and "High". I tried them all and
found that Medium solves the problem and I now have USB 2.0 working at
correct speeds although the connection keeps getting dropped and refound.
Logged another call with ASUS to find out what the settings are and how I
should set it up and have had no response at all!

I also have the exact same problem with the Sis chipset on the Abit SR7-8X
MB. I have tried installing removing reinstalling drivers and service packs
with no results. I decided to do a fresh install of XP with SP2 on a new HD.
The OS didn't recognize the ehci usb device automatically. I had to right
click on the device in dev mgr and update driver. It then added an Enhanced
USB controller to the usb list. However when I plug in the usb 2.0 HD I get
the "High Speed dev plugged into a low speed port." Unfortunatlly there isn't
any USB specific settings in the BIOS for this board, only enable or disable.
This seems to be a wide spread problem occuring on different MB's and
chipsets. I have to wonder if Microsoft is aware of these issues, they seem
to be the only source for usb 2.0 drivers under the XP platform. Either way
USB 2.0 doesn't seem to be a very well supported standard.

:

after I read some posts, I found there were a few problems with sp2.......
the only word I can say now is.........be patient.......
Or you can buy something else to replace your usb hardware......
For example, buy a combo cdrw instead of a usb cdrw.............
