For one project I'm currently working on I made pic related (top pic). But I would like to do it all through just the USB cable, but the LEDs can suck up to 3A.

Will I burn my PC-port or the thin USB wires if I try bottom pic? If not, what about the floating voltages? Do I need to connect the ground to both power supply and PC? Is it a problem the 5v from the data line not the same 5v as the one on the plus wire?
