Hi
I was rewiring my home made arduino to use a type B usb connector instead of type A as that's the usual standard. The entire circuit has many gnd wires , so to keep it tidy I decided I'll tie my usb connector directly to my dc jack. However the usb connection stopped working immediately. When soldered it to the gnd pin of the regulator it works. why?
