Yes indeed - in my case it was a Logitech Cordless Mouse - I don't know if
in this case changing BIOS settings would have helped - however even after
a shutdown and power off, and then booting from scratch now gives mouse input
that is properly recognised without the need to pull and replug the usb
connector.
