This sure looks weird and messy. My first idea was that it could be a fake, but the
Phison PS2251-08 looks legit and seems to be used in Kingston flash drives.
Actually, on the pictures it looks as if the upper 5 pins were cut on the connector. Also there seems to be a botch wire between the fourth and fifth pad (counting from upper to lower side).
Without that botch wire, I could imagine something like that could also happen in production if they get a defective USB 3 connector. If there really is a botch wire, it must be a repair attempt.
Which raises the question about the origin of this thing. Was it bought new from a retailer or from some guy on eBay?
[EDIT]
Side note: if the upper five pins are not connected, both, the superspeed transmit and receive LVDS channels (full duplex) are missing. This leaves only the D+/D- (half duplex) USB2.0 LVDS lines.
