The other day I plugged my usb cable into the usb port on the control board for the first time and I got no signal on the GUI. So I went to remove the usb cable carefully and the port mechanism came off the board in my hands. Manufacturing glitches happen, so no worries, but can someone tell me how to reattach the port? Can't tell if the metal contacts at back are supposed to fit against the board by pressure, do the feet of the unit solder onto board? Can't really tell--need a magnifying glass. I'd really appreciate help. Thanks!
