It could be a USB cable problem if you are using one or USB cable extender?<br />
<br />
Try to change the USB port on the computer also.<br />
<br />
As nobus said, uninstall the driver software completely, restart the computer and then install software and connect the USB when it prompts.<br />
<br />
This should solve the problem.<br />
<br />
Good luck.<br />
