OpenTherm Gateway USB cable

Hi Guys,

Might be a bit of a weird question, but while moving into another home my OpenTherm Gateway USB got loose. Now i have to reconnect it, but i have no idea which cable i have to put where.

Any smart kid that knows the answer?

Can’t see gold pins on this picture :frowning: Data (white and green) wires are connected. In the air you got: ground (black) and Vcc (red). So You need to connect USB ground (black) to ground on PCB.
