USB stopped for no apparent reason

[Guest]

Today I turned on my computer and noticed that the USB Microsoft 6000 mouse
had stopped working. So has the Epson USB printer. Tried everything to get
them going again but nothing. They have been workiing quite happily for he
last two months I keep getting message that the device has malfunctioned.
Changed mouse with another working USB MS mouse off my XP machine still
nothing. Other posts say click on this, click on that - how if mouse is not
working? Seems a lot of people are having problems with USB devices (my sons
USB mouse has stopped working on his Vista Laptop). Has anyone else found a
solution? Has microsoft found a solution?

Try getting only the keyboard working first. Start with a POWER OFF.
