Meaning of the landlord is to position the conductive pads remove this circle, you can solve some of the big mouth and a standard USB failures, because the factory, the workers posted to the conductive pads are too close to the pin next to the manifold, causing the chip short circuit resulting in failure of a large USB plug any device does not recognize, so get rid of the pad or move about the location, so it does not touch the manifold next to it.
Great usb bad promising self-repaired, disassembled will find a contact with the conductive cotton to other components on a small usb, causing a short circuit! Removing conductive cotton, cotton swab to wipe more than glue, to solve! This method is derived from the CUBE exchange group
