USB ports do not function

I am totally confused. We have 2 computers that the usb ports are not working. The ports show up in device manager, I have removed them in safe mode and during reboot they reinstalled. However, when plugging in a device, natta, nothing. Both computers are ASUS MB's, prc800 deluxe with a raid array and a p4r 800-mx. I'm thinking both computers quit working after SP2 update. I even tried rolling back the usb drivers to an earlier date. The BIOS is set properly and updated to the most current version. Installed a usb card which installed normally and works. I can't imagine this being an issue with the board since the drivers reinstall after they have been removed. I also unplugged all addon usb's from the board and just left the 4 or 6 on board ports.
Thanks for any help..

Did you check cabling? (motherboard connectors)
Can you do a repair install?

I unhooked the cabling, leaving just the usb ports built into the mb and I did a repair of the os. chkdsk /r I didn't do an inplace upgrade or remove SP2.

u might need to check the USB Emulation setting in the BIOS

Remove the usb drivers from device manager and restart. When restating go into the bios and disable all usb devices and then startup into windows.

Next thing to do is to restart and got into the bios again and this time enable all usb devices including legacy device and stratup into windows again which will of course find the usb and want drivers.

Let us know what happens.

This is baffling without a doubt. Could it be possible the board is bad?

Did u recently connect any new devices to the systems that installed drivers(SP2 may be guilty)? Sounds like the usb drivers may have been over written, I had a similar problem when I installed a USB steering wheel. The hardware install replaced my USB2.0 drivers with USB 1.0 and every time I tried to remove them, windows automatically reinstalled the incorrect drivers. Also is this sympton appearing in just one case or with any hardware u attach? What hardware won't show up? Try this, install the Intel chipset drivers for your mobo(875P, small typo in your q, I figured u meant Asus p4c800 Deluxe), that should correct the prob: http://downloadfinder.intel.com/scripts-df/Product_Filter.asp?ProductID=1043
Just select your OS and grab the first download in the list.

Hey freeman118, that didn't work either. I came across a help file today, thought I'd bookmarked it, but didn't. Anyway, it talked about renaming an intel file and re-installing it. Will look for it tomorrow and post if it works. Thanks for the help.

<< I have removed them in safe mode and during reboot they reinstalled.>>

So I presume you are running XP -- say which one with USB, because 98-ME doesn;t work right with USB, but XP does...

It's kinda simple -- on the ASUS MB, you MUST MUST download the USB utility from their website -- see here --

http://www.asus.com/support/download/item.aspx?ModelName=A7N8X-VM&Type=All

Select your MB, select the USB update -- without this, the ASUS does NOT recognize all the USB ports correctly.  Once you have installed that, I KNOW it works in SP1.  If you are still having trouble it has to be a SP2 issue, as SP1 works flawlessly, once you install that crucial update for USB !!!!

Another thing is, I plugged in a USB optical mouse into all the available ports and the infrared lights up solid then starts to blink rapidly. I then went into device manager and checked the power on all usb ports and it isn't showing any power assigned...

If u still have no luck could u perhaps tell us what devices u are plugging in? What does Device manager call your usb host controllers? sciwriter: what USB utility, I dont see anything except for 98 drivers, plus wrong mobo, p4c800 at: http://usa.asus.com/prog/spec.asp?m=P4C800%20Deluxe&langs=09

sciwriterCommented:
Look you HAVE TO select the correct MB type.  If that screen doesn't work for your MB, then simply go http://usa.asus.com and go through ALL the screens to get to the right MB type -- it isn't that hard, but one has to use the site to get the right MB drivers.  I assumed hammertime would ALREADY KNOW THIS since he seems savvy -- there is no need to get stuck at a link wher you can't just pick the MB type !!!

MS doesn't provide the right drivers for the ASUS board, if you actually READ the ASUS docs, you will see this, you need the ASUS USB drivers, not the MS ones.

freeman118Commented:
easy... Now on the Asus site(http://www.asus.com/support/download/item.aspx?ModelName=P4C800%20Deluxe&Type=All) it states usb for 98 and win2k, is this what u are talking about, I don't see anything else USB.

Try this as a last resort before you need to reinstall windows XP cleanly with a format. Nuthin short of that will solve ur problem.

Go to the Control Panel >System>Device Manager and check for a setting called "PCI to USB controller" under either USB Controllers or Motherboard devices and then select update drivers. Windows will ask you the location, just press next and let windows finish installing the drivers. Now restart the system and see if it works.

just one question :  did those ports ever work?

and another one : is it a new build? and did you install all the drivers for it?

Hammertime2Author Commented:
The ports have always worked and the puter is approx. 6 months old. The customer brought it in yesterday and I was hoping I wouldn't have to reload since it is a business machine with specialized software that will require a considerable amount of configuring. Like freeman118 stated the Asus site lists usb for me,2000 and 98. I investigated all these options before posting.
I don't understand the post  from sciwriter about MS doesn't provide the right drivers for the ASUS board. We have never had to load special USB drivers on a new build since XP loads them, always.
Thanks again for the input. I going to do a little more searching before dumping the box and starting over.

freeman118Commented:
Yeah the pci to usb host controller was what i was getting at when I asked Hammertime to install the Intel 875P chipset drivers(they include the usb drivers). Still cant believe that didn't help, Hammertime: when u ran the install for those drivers, did they reboot the system and after restarting guide u through the install? What does device manager call your usb host controller(full name)?

nobusCommented:
i would then think that it is related to an install or upgrade of software; check if a system restore does not help you out. or uninstall SP2
The other option would be that the ports went bad, but this is unlikely.
I work all the time with Asus, and never had to load a usb driver within the last couple of years

Will update in about an hour, loading windows on a different drive to rule out mb issues.
 The usb devices are - Intel 82801EB usb host controller - 24d2, 24d4, 24d7 and 24de as well as the USB root hubs.
The Intel chipset driver update was successful and updated the usb drivers to the most current.
If this turns out to be a SP2 issue, it would be nice to figure out the problem rather than reformatting the drive. This issue will arise again in the future with more and more computers updating. Like I mentioned in an earlier post, we have another computer on the bench with the exact same problem. Never before has this happened with USB issues and now 2 computers in the same week with similar usb problems.
If the fresh load does not cure it I plan on changing power supplies just in case it's a power issue...I also pulled the board, in the off chance that it had shifted and was shorting.

Hammertime2Author Commented:
Well, turns out it's a MB issue. After a different hd was installed with windows and a different power supply was installed there are still no USB ports. I will contact ASUS for a replacement.
Thanks for all the input almost all was helpfull.
In a case like this, and I'm new to Experts-Exchange, are points to be assigned to anyone for the work put into this?

freeman118Commented:
Yeah, sorry there was no solution for u here, but maybe u could tell us what Asus has to say, after u contact them.

Hammertime2Author Commented:
They are RMA'ing the mb. They thought that maybe 1 pin has been shorted out. Will follow up when I know for sure

freeman118Commented:
Thanks for the points hammertime2, though i didn't provide an actuall answer hope u got things sorted out. FYI SP2 replaces all harware vendor USB drivers with MS drivers, this is a good thing and a bad thing, if u try to replace the drivers windows will over write them with the sp2 drivers. I hope that is useful.
