I have had this problem on XP since reformatting. And this is the only way I have been able to solve this problem.
try reinstalling the USB driver or try with other port If still the problem is there try connecting the same Pen drive to other system if its working fine that might be an operating system issue.
1.Try to install the USB driver take help from the microsoft .com there are some file that we need to register for USB from this command regsvr32 just check for the file name from microsoft that you have to register.
2.Try to remover upper filter or lower filter from registry
3.Try to uninstall all the USB device from device manager.
Still face the same issue might be an issue with the Pen drive that you are using
Try to search the best diver software in to the internet or make sure your usb port are no damage.To check if your usb port has no damage try to use another one if its not try to update all your system drivers using driver updater software.
