Hello,I'm not a very advanced user but I rebooted my computer a few months
ago because I suspected some kind of virus. I found subsequent to rebooting
that none of my USB ports would work or be recognised in My Computer. Any
help would be gratefully recieved.
Thanks.
Will.
 
Will, try rt clicking MyComputer>select Properties>Hardware>Device
Manager>USB Controllers>rt click on each one and choose Uninstall. Restart
and let XP reinstall them.

Did you find out if the system was infected and if so were you able to
remove the malware?

To "reboot" a computer is to restart it. Most people do it at least
once a day.

Undoubtedly you mean something else. You probably mean you
"reinstalled" Windows. Please clarify that that's what you did, and if
so, tell us exactly how you did it.

ago because I suspected some kind of virus.

Why did you suspect a virus? What symptoms did you have? Do you run an
anti-virus program? Did it tell you that had a virus? What virus was
it?

After you "rebooted" (or reinstalled Windows) did the virus go away?
How did you know?

How do you know? Please explain exactly what you did and what the
results were. If you got an error message, please quote it verbatim.

"My Computer" never recognizes USB ports. It does recognize drives
that are plugged into USB ports. Again, please describe exactly what
you did, what happened, and what you saw.

Please answer the questions above, and I'll try to help.

There is one hardware chip that can actually have all its
USB ports fail at the same time. That is the Intel ICH5 or ICH5R
Southbridge. So it can be explained as a hardware failure. To
identify that case, I'd need to know the make and model of
computer or of the motherboard inside the computer.

The USB driver comes with the OS, and USB2 would be present if
you had at least WinXP SP1 service pack.

http://www.usbman.com/USB 2 News.htm

"Microsoft Win XP USB 2.0 drivers are included in Service Pack 1.

Microsoft Windows 2000 USB 2.0 drivers are included in Service Pack 4. "

You should check Device Manager, and look in the "Universal
Serial Bus" section near the bottom. Some examples here. What
these entries show, is the hardware inside the Southbridge.
This is not a listing of "ports" but of the logic associated
with USB inside the Southbridge.

There is a utility that can show things plugged directly
into your computer USB ports. You can get a copy from
one of the dated links on this page. (UVCView.x86.exe)
Microsoft used to offer this for download, but removed
it. The archive has a copy of it.

http://web.archive.org/*/http://dow...f-a31d-436b-9281-92cdfeae4b45/UVCView.x86.exe

In this screenshot, you can see three "Device Connected" entries,
and the data from one connected device is shown on the right.
This is from an earlier version of the utility.

I had the ICH5 USB problem with my Asus P4C800DLX and unlike the OP, the
ports were recognized by Windows, they simply didn't work.

If the OP reinstalled Windows (rebooted???), maybe he hasn't installed
the chipset drivers and that caused his problem, just a guess.

Go to Device Manager and look under USB devices. Are there any yellow
exclamation marks?
