First of all you need to check whether the lock behind your scanner is open or not. If not, unlock it.
Two, if the secure lock has been opened already, but the system is still incapable of identifying your USB device, you can check if you have installed a scanner driver or if the driver is correct for your device.
Step 1 Find out your scanner model.
Step 2 Check Scanner driver in the Device Manager sheet.
Step 3 If you have not installed a driver yet, or the driver is incorrect, search on the website and download the supporting and latest driver for your USB scanner. Before installing the driver, uninstall the incorrect one. Note that when you install the driver, make sure it works well with your system.
Three, you can try to swap your scanner onto another USB port. Because if the cable order in this port is not right, it would also generate the failure above, which often happens in the motherboard's front USB port.
Four, your motherboard might not be compatible with your scanner's port, so you are unable to find out this device in your computer. To cancel it, you need to check the model of your motherboard chipset, download its latest driver or the corresponding motherboard USB patch from the website and then install this driver or patch.

I did not think the question would be posted yet so that is why it is so brief. There is no response at all from any USB port. I can still read cds but it would not let me burn an Win_7 ISO. It says it cannot read the disk at nearly the end of the operation.
Thanks Brian but it's mainly the usb issue that I need to fix.

In Device Manager, double click to expand Universal Serial Bus controllers, right click on the Host Controller, click Uninstall and click OK. Repeat the step 2 to uninstall all items under Universal Serial Bus controllers. Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. for XP or earlier click start right click on computer select properties device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X you will need to update/reinstall drivers right click to reinstall drivers if you can see your usb drive but its not working ports (com&lpt) right click update driver if this fails to fix the problem Check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts
