I have the same problem. Try uninstalling and reinstalling the driver.
If that doesn't work, try updating the driver.
And if it doesn't show the file that is required to update it, and everything else says its not made for the computer, and in your list of usb devices, it says, Unknown Device...then you got it a bad as I do. Can anyone help me with mine also? I uninstalled, reinstalled, looked at the forums, and nothing worked..
