PINE64

Hi!
I just received my board and as I see there is some kind of solder on the bottom side under USB connectors, besides there is thin threads from this solder goes to the USB2 connector
I have not received power cord, so I can not test it, can anybody say is it normal? see pics

Its clearly a manufacturing mishap.  Heres mine.

Yeah, as Luke said, it's not normal... here's what the bottom of the pre-production rock64 looked like... (I don't have a pic hand of the v2 release rock64 handy, but it's essentially the same without the superglue )
