Q: Windows XP: USB mouse and keyboard stopped working

After one of the Microsoft Windows updates my USB mouse (Logitech) and keyboard (Dell) stopped working. They are working before login screen and working if I boot from Symantec boot disk. But I cannot login at all because I cannot go through the login screen. Been looking ovet the net for a week - tried some suggested solutions (like add another USB PCI, etc.) - nothing working. I can use keyboard in BIOS settings (all USB legacy is enabled). Computer - Dell Dimension E520, XP pro. And I do not have PS/2 ports unfortunately. Not sure it will work if I will add PCI with PS/2 ports...




Done unplugging all devices - no changes. tried to boot in Safe Mode with Command Prompt -no keyboard or mouse...

Here are some snippets from DELL website, please take your time to read it and apply as required:

Make sure that you are using the correct ports and also read extensively about theI/O-Panel Components on one of the links provided below.

To ensure the device is attached directly to the port, verify that the USB cable runs directly from the peripheral to the USB port, with no intermediate devices in between.

On the same Page above Under "Maintenance" see this option I mentioned in one of my earleir post:
