Well it smoked, and the parts that burned on the mobo are U9 near the USB port and Fuse F3.
This is bad USB circuit, as when I got close to the shield on the USB and plugged in my PC USB cable, I noticed sparks.
Then tried again no sparks, 28 hours later I was going to print via USB and then it smoked. This can be fixed easily with a replacement mobo.
and redesign of the board USB.
