anyone has a solution for connecting to power directly to the battery connector by usb?
I thought used a 3.7V zener diodes in parallel between the - and + USB power and a series resistor.
I've used LP3874. You'll need a fair bit of capacitance in order to transmit.

Is it possible to combine both signal and power lines within one usb cable? Would love to see schematics.
