I really wish hardware makers would PAINT that side. I have no interest spending more than one neuron-firing figuring out which side is up by looking at both sides under appropriate light. I've taken to spray-painting my USB connectors, in a nice steampunk hammered copper. If a device needs connectors to be face-down, I paint the down side (i.e. the "real upside") of the socket on the device, too.

I don't care about the 0.2mm USB logo relief. PAINT that stuff up. Contrasting colours, with the USB-logo side BRIGHT and SHINY, please.
