Just done little improvement:
thanks
d-Artigo for Your hard work.
Alien-4 You need make connections like on attached pictures, then Your USB function should work fine. Z3301 is for USB connection and V3310 for charging:
- Without V3310 You can still charge and use Your phone, but You cannot connect via microUSB to any device.
- Without Z3301 You can't charge phone, You can't connect via microUSB as no power feed for V3310
