check your system problem or your pen drive problem..

first u check system root hub....

if u have problem in root hub u can't open your pen driven in your system..

if u don't have problem in ur system first try to format the pen drive..

after u can plug the pen drive in root hub and play ..

u can easily identify pen drive problem or system problem...............
