Hi I have my sisters computer, dual boot Suse/windows. Both Linux and widows indicate that the USB ports are configured, but no USB devices are configured or found when plugging in. Not even the "light" comes on with a USB mouse or USB external drive etc. Have tried Knoppix with same results. 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? Kind Regards

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!).
Thanks Adam

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

Hmmmn, looking at that suggests the machine can see the USB hardware but nothing on the bus. Like Wayne suggested get a test meter on it to see if there is any power going over the USB bus. I think some machines might have a resettable fuse on the motherboard for usb things so it may be worth having a look at that possibility (of course many motherboards have a fuse on the USB circuitry but once the fuse has blown you can't replace it easily, if at all).
You /may/ end up having to replace the motherboard or look at getting a pci card with USB ports on it, I recently got a USB 2 pci card with 4 external ports and 1 internal port for a grand total of £6.48 off ebay.
Thanks Adam

Hi Adam Just finished checking with voltmeter, no 5V present on USB, cannot find fuse or reference to it in otherboard manual. You have also answered, my other question re. pci USB cards, as to whether they work OK on Linux, (last time I tried one was Suse 7.0) Will fit pci USB Many thanks for help all. Kind Regards -Nick Daniels

Be careful exactly which card you buy, not all of them are equal. Try googling the exact chipset numbers before you part with your money. Most of them will work, just some work much better than others (in Windows and Linux) and the better ones sometimes cost less.
Thanks Adam
My IBM Thinkpad did that to me after I plugged in the cradle for my Nokia 9300 (at least that was the last thing that worked on it)
Same behaviour as you...USB interface hardware was present and working as far as the OS knew..but nothing responded when plugged in to a USB port.
In the end it had to go back to IBM for a new Mainboard under Warranty.
On your machine. have you only tried the front ports ?
There are a few different wiring conventions for the USB header, it's possible that those ports wired on the header are wired incorrectly (it is also possible for this incorrect wiring to shut down the USB interface but usually the OS knows about this)
So I'd try using one of the ports that are directly connected to the mainboard (on the rear I/O shield panel) and preferably also test these with the front panel header disconnected.
The problem you have also sounds a bit like a missing 5 volt USB bus power supply.
If you have a test meter handy then you can sacrifice a spare USB lead by stripping it back and testing for 5volts across the red and black wires inside.
