Hello,

There is a small program that test the USB ports
USBView is a free utility from Microsoft that displays the USB connection tree and shows the USB devices that are connected to it together with their configuration data. This is very useful for debugging USB enumeration errors. USBView runs under Windows 98, ME, 2000 and XP.
Download AND execute USBvew
