Is it possible that all the USB ports have failed? Have checked on Google and only found reference to this with one specific MSI motherboard, this is an Asus Is there anything else I can try or have overlooked?
It certainly does suggest that the ports are all dead. Try typing lspci into a terminal window in linux and look for lines similar too:
0000:00:0f.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63)
If you don't see any lines about a USB controller then it is either that the USB ports are turned off in the bios on the machine or they are faulty in some way.
If you can see a controller then try plugging in a USB device and typing the command lsusb, look for lines similar to:
Bus 003 Device 002: ID 046d:c506 Logitech, Inc. MX-700 Cordless Mouse Receiver Bus 002 Device 003: ID 04e8:3242 Samsung Electronics Co., Ltd
You can then type lsusb -v for more information on the devices, if you don't see anything after plugging in the device and typing lsusb you can try typing the command dmesg too see if the kernel says anything about the device being plugged in or if there are any error messages.
Let us know how you get on as your problem could be one of quite a few things (although if the devices don't show up when you run lspci there is a good chance that they are not working!).

Have not changed Bios, was my computer for two years and was present to her two weeks ago. Thanks also Wayne, no front ports, will get test meter on it tommorrow, when I get battery.
parts of dmesg hub 5.0.0.1 8 ports detected Will fit network card so I can copy other computers messages to email
Many Thanks - Nick Daniels
