USB Not being detected

I am new to this but in search of an answer.

When I plug in any USB device I can see the light flashing on the device (power getting to it) however it does not detect the device in my computer or does not show in disk management. I am running windows XP.

I have been reading up and heard a few answers on forums like this but none have been proven to work, these included:

Resetting BIOS settings to default
Enabling USB legacy support in BIOS settings
Deleting upperfilters and lowerfilters in the registry
Deleting USB drivers and reinstalling

If anybody can help me please reply as I am at a dead end and not sure what to do.

Kind Regards,

Hi :) 

Are your service packs up to date as there were some fixes for USB in SP2 and SP3 ???

I am not very good with computers If I am honest, I don't know what a service pack is.

Surely they shouldn't just stop working? I have re-installed windows again but no luck.

This may just be a power issue.
I have seen it many times, especialy with USB Hard Drives.
If the USB cable is detachable, remove it and try another (usually thicker is better).
If the device also has a power supply or second usb power cable use it.
Try connecting to a usb port you know is working.
Try connecting to a different computer.
If after all these your device still doesn't work, its probably dead!
