On the original Pi Zero PCB these test points are labelled PP1 (5V), PP6 (Gnd), PP22 (Data+) and PP23 (Data-). The gold circles on the rear of the Pi Zero are test points. Here is a diagram showing the “3D Sound” audio module PCB connected directly to the USB port on a Pi Zero : An example of where you might want to do this is in a handheld gaming system based on the Raspberry Pi Zero. Theres a program called BitPerfect which is a very cheap solution to that problem (without migrating to an entirely new architecture and dumping existing one).
