Come to think of it. This problem was happening way before I put the pci card in there. I only put the pci card in there because I was having this problem!

BCCCOMP, Did you see anything in that Everest file I sent?

I'm only saying that we should troubleshoot one problem at a time. The fact that you can't uninstall the pci to usb device in the device manager is a problem we should get rid of before troubleshooting the usb ports further.

Whatever caused your integrated USB ports to stop working back when you had XP MCE would probably have been solved by a reinstallation of MCE using the CD that came with the computer (unless you can think of something that could have physically damaged the usb ports). You never installed the proper radeon X200 chipset drivers on XP Pro before using the PCI card, did you ?

garypriceomaha

I gotcha. You guys are the experts and I really value your help. I'll reformat and start over without the pci in there and report back to you.

garypriceomaha

O.K. I'm all done. Here's what happened:

Wiped the drive, installed xp pro, installed drivers, installed sp2

This first picture is where I was at after installing all the drivers. It found all the usb's except for this one so I left it alone thinking sp2 would find it and install it.

Installed sp2 and it still did not automatically detect it so I "updated driver" and it found it and installed it.

Results:

After installing all drivers pc working great--0% cpu usage.

After updating driver on the lone usb cpu usage back to 100%

???? ARGH ???? :(

Hi Can you do me a favor?
Remove the nvidia video card and the drivers.
Connect the PC to you on-board card
Enable the On-board video in the BIOS
Install this chipset driver:
http://game.amd.com/us-en/drivers_ca.../integrated-xp

Reboot the PC and see what the CPU usage is.
See what errors are in the Device Manager.

Thanks,
Bill

Installed the ATI video drivers and took out the nvidia drivers and software. Rebooted several times. Still 100% cpu usage and no errors in device manager, but I am the proud owner of a free trial of World of Warcraft thanks to ATI :)

You were on the right track though. I think we figured out that the video card is a PCI Express card so that's why it was loading the PCI Enhanced stuff. Am I right?

Don't think it will matter but should I now do a fresh install without the nvidia video card installed? or what?

Am I the longest thread you guys have had to try to figure out? I really appreciate you trying to help me.

When it's all said and done could this just be a hardware problem?

The "standard enhanced pci to usb host controller" was definitely related to the PCI USB card, not to the PCI-E video card. "Enhanced" means USB 2.0.

Using an nvidia video card on an ATI chipset can cause issues so I agree with BCCOMP, it's a good idea to fall back on the onboard video card (I hadn't realized that you added a dedicated card). Btw did you upgrade the power supply when you added the nvidia GeForce 6600 video card ? The original supply isn't likely to be sufficient for a dedicated card and USB issues can be caused by an underpowered supply. If there's an hardware monitor screen in the BIOS check the voltages.

It would allow to rule out conflicts between the Ati chipset and the nvidia drivers and problems caused by unsufficient power.

Formatting and reinstalling each time a problem happens isn't the most efficient solution, let's do this :

1. Remove all the PCI cards (video and USB) that weren't with the computer when you bought it
2. Enter the BIOS and reload the default settings to make sure nothing's wrong there. Check the USB settings and report their value (should be enabled, hi-speed, enhanced or USB 2.0, any other value could limit them to USB 1.1)
3. Install XP SP3 (slipstream SP3 on your XP Pro CD)
4. Once within Windows enable XP's integrated firewall before you connect the internet cable then follow these instructions to make an image of the system with DriveImage before you install any drivers : How to Backup your boot hard drive.

Now if/when things go awry all you'll need to do is reload the previous system image using DriveImage and the Bart PE CD (takes 10 minutes) instead of reinstalling from scratch.

Then experiment with the drivers. I strongly suggest that you start with the radeon X200 chipset driver that's on eMachine's website :
http://www.emachines.com/support/pro...es&model=T6524
Then install the AC audio, ethernet, media reader and modem drivers. If all is fine connect to windows update and install the latest critical updates for your system. If things go bad at this point tell us about it and reload the clean image.

According to your system specs there are 7 USB ports :
See how they work before and after you install the drivers, test the 4 rear ports and the port in the media reader, no need to test the other 2 front ports. Also before you install the drivers and are on the situation that's on your first pic what was the status of the "unknow device" and of the "Universal serial bus (USB) controller" with yellow icon (double-click the device to see the device status) ?


Another way to look at the issue would be to analyze the kernel to find what particular driver is using the CPU. I provided the tools for that in post #8.

BCCOMP

What are the complete specs of the PSU.
The specs are listed on a tag attached to the PSU
Thanks,
Bill

garypriceomaha

I'll experiment with this.

I'll see if I have a more robust psu laying around. I've kinda gotten to be a collector of old pc's over the years.....BUT If I don't use the add-on video card I shouldn't need a more robust psu, correct?

justpassingby

It didn't load again. The first time you reinstalled XP you let the card in and only took it out after XP was reinstalled, the device had been found during the installation which is why it was appearing in the devices list. The last time you reinstalled XP without the PCI card and that "PCI to USB" device didn't appear.

As I said on the first page 11.6V is low for the 12V line. The ATX specs state the voltages need to remain in a 0.5% range of their nominal value, the closer the better, and 11.6V is exactly 0.5% away from 12V. The computer would probably crash during games due to the video card being underpowered. What are the voltages now that you removed the PCI-E video card ? What's the brand and model of the power supply ? (check the sticker on the side of the power supply block)

I'll check the psu specs tonight when I get home.

The "pci to usb" device did appear. See my 2nd picture.


"This first picture is where I was at after installing all the drivers. It found all the usb's except for this one so I left it alone thinking sp2 would find it and install it.

Installed sp2 and it still did not automatically detect it so I "updated driver" and it found it and installed it."


All the above was with out any extra cards in any slots. No video, no usb, no nothing. So I don't know how it could detect something that's not there! Maybe it's seeing something hooked up via ide that it's counting as pci?

garypriceomaha

The psu is a atx-300
It says 300 watt max and still says 11.6 max

BCCOMP

HI,
Do not get confused with the Enhanced USB Controller. This is needed for USB 2.0 speeds. This will load each and every time whether or not you have the USB 1.0 card in or not. This is due to your Motherboard having USB 2.0

On the PSU there should be more info. Can you post ALL the info you see on the tag.
Amps
Voltages
Watts

garypriceomaha

http://www.ascendtech.us/itemdesc.as...30012E&eq=&Tp=

This is the exact model number

Bestec atx-300-12e

It says on the psu:

input: 100-127v-6A
200-240V-3A 60/50 Hz
output 12v-15 amps
-12v 0.8 amps
300w max +5v +3.3v
+5v & +3.3v 180w max
+5v & +12v & +3.3v 288w max

BCCOMP

HI,
This PSU is way under powered for your PCI-e card.
A Pci-e card requires 26Amps on the 12V Line

If you had run this PSU on your PCI-e card then there is a good chance damage may have been done to the motherboard.

That said I believe your issue with the 100% Cpu usage is your USB controllers.
But lets see if there is something causing this.

First have nothing connected to ANY USB Port (Keyboard, Mouse, Printers etc.) or USB Headers (Media Card Reader etc.) on the Motherboard.
Once you can confirm NOTHING is attached that has anything to do with USB, see if you still have 100% CPU Usage.

Bill

garypriceomaha

There is nothing connected to any usb nor do I have any pci inserted at this time. Other than the video card I have not had anything connected during this last install of xp pro and now it is out also. Still have 100% cpu usage.

garypriceomaha

Going back to post #44--Everything was fine until that one usb driver was "updated"

BCCOMP

Do you have a Media Card Reader?
Bill

garypriceomaha

yes, onboard though.

BCCOMP

It uses a USB Header on the Motherboard I believe. You may have other devices connected on other USB Headers.
