My Main computer has somehting wrong with the USB so I have to use my second computer. Will it work intermittly with the data line reversed? I know the power and ground is right. Sometime when I plug in any device it recognizes it and some times it doesn't. I remember the wires on the motherboard were not maked and I am going to look at it. What should I look for?

No, if the wires were reversed it would never send the program to the micro.

Thanks Rick It must be a loose wire then but the funny thing is both front usb sockets do the same thing.
