Pen drive not detected

Hello,

my computer did not detect my pendrive
it was okay before put the problem started last nite
when i try to connect the drive to my computer, nothing happened i.e. it wasn't detected at all

but when i try to connect on other computers
certain computers did detect the drive and some were not

do you guys have any idea what happened?

oh..
by the way
i had tried to connect other drives on my computer and the drive were detected which means my usb is working properly
