honestly ive really tried everything on this site im getting very frustrated but i know you guys do your very best. with that said i thought, in fact, i know that my pc can not recognize the device in the usb because it cannot find the proper driver assigned. But after many hours trying to find it i relized it comes with the software CD that i had misplaced soooooooooooooooooo how do i go about installing a program without the proper disc or driver. I run on windows xp home edition with my mzn420d
