USB problems.

Whenever I seem to plug anything into my usb ports, nothing happens.

I've un-installed the usb drivers from device manager, re-booted and
installed again, nothing changes.

I disabled USB, and re-installed drivers from the motherboard CD,
nothing happens.

I checked to see that the USB ports were actually plugged in correctly
in the motherboard, and they seem to be..
In any case, I un-plugged them and plugged them back in, still nothing
works..

They must be plugged in correctly, anyway, as windows XP recognizes
them and installs their drivers..

Is there anything that could be disabled, which would be causing this?

I tried plugging in my digital camera, and it doesn't work..
I plugged in my webcam, and nothing happens.. The programs that I use
to run the webcam (netmeeting, and the logitech program) tell me that
the camera is not plugged in..

I plugged in a USB mouse, as I thought that perhaps it was the
peripheral's drivers which might be causing this, but no.. the mouse
doesn't work either..

Any ideas what it could be?

what does that mean?

It means that your hardware may have failed. If no usb devices work in
the usb ports, the usb ports on the motherboard may be broken. There
are a couple of ways to test this. If this is a desktop, you can put in
a usb controller card (they are quite inexpensive). If those ports
work, then you know it isn't an operating system issue. Another way to
test the hardware - or if you have a laptop and can't stick in a PCI
card - is to boot with one of the Linux live cd's like Knoppix. If the
usb ports don't work with Linux either, then you know for sure the
hardware is broken.

I'm thinking it must be an operating system thing, as I have a USB
controller card, as well as the usb ports in front of the computer..

And none work..


If it was Windows causing this, what could be a way to fix this?

Just wanted to add my issue to this since it seems to be the same (rather
than start anew thread)

I have a machine here that is experiencing the exact same problem as the OP.
Everything was working fine up until a couple of weeks ago, though there was
no specific instance with which this problem seems to have coincided.

Also of note, when I plug a device into the usb port, it does get power from
the usb port. Its as if Windows XP is just ignoring any devices plugged into
the ports. (no sound as per usual when a device is plugged in)

The motherboard in question is a Gigabyte GA-8IPE1000 Pro-G

Thus far I have tried with no success:
Repair install of Windows XP;

Delete and reinstall the drivers for the usb;

at the command prompt typing set devmgr_show_details=1 and set
devmgr_show_nonpresent_devices=1 then running devmgmt.msc and choosing "view"
show hidden. Which then displays every USB device that was installed on the
machine. I deleted all of them, then rebooted, and again no effect;

Tried Manually updating the drivers;

Set bios to only use USB 1.1;

Updated motherboard BIOS to latest version;

Cursing at the machine;

backing up, deleting and installing registry keys from a machine with
working USB;

I tried installing a PCI card with 4 USB 2.0 ports into the machine, and
whenever I plug anything into it, the whole machine locks up completely.
(this happens with usb enabled or disabled for the motherboard ports). The
usb Root hub shows up just fine in the device manager though.

I've even repeated a few of these steps numerous times to no effect (I once
read the definition of insanity is trying the same procedure over and over
and expecting different results heh).

When I plug any usb device in, there is absolutely no indication from the OS
that something has been plugged in.

As mentioned by the OP the device manager lists the USB hubs just fine and
says the devices are working properly. I do suspect that there has been some
kind of software installation/corruption that has perhaps locked out the USB
ports, but after hours of searching through various sites, have found nothing
to solve this.

Any tips/suggestions would be much appreciated. Total Wipe is a very last
resort I'm afraid.

Thanks

Firstly have you tried a 'System Restore' to a time before your problems
started? If not I suggest you do that.
Secondly, have you run sfc /scannow? If you haven't I suggest you do so.
Thirdly, do you have an image of your system. If you do and all else fails,
you can restore your system using the image. Backup all data files
beforehand to a cd so you can restore your most recent data afterwards.
If no image you can run 'repair' from your install;ation cd but only as a
last resort.

Edward, thank you for your suggestions they are much appreciated.

Embedded responses.

:

Tried and unforatunatley it didn't work.
Secondly, have you run sfc /scannow? If you haven't I suggest you do so.

Didn't do this, but after I imaged/rebuilt there was no point in continuing
looking for a software issuse :)
Thirdly, do you have an image of your system. If you do and all else fails,
you can restore your system using the image.

This was the very last thing I tried. I imaged the machine, wiped it and
built from scratch and as it turns out, this too did not get the USB ports
back. So the issue must be a hardware failure (though it is odd that the
power is still coming through fine)

Backup all data files
If no image you can run 'repair' from your install;ation cd but only as a
last resort.

Did a repair from the install CD first actually, but to no avail.It would seem that this problem is a MB issue, although it is every single
USB port on the board that is dead, while everything else is running fine.
But a complete rebuild from scratch (wiped partitions) and even trying a dos
boot disk with dos level drivers wouldn't get the ports to read.

Thanks for taking the time to try to help.

Cheers
D
