BQ25887: BQ25887 Valid USB power detection

Part Number: BQ25887


I am using in a prototype a BQ25887 and willing to use it with the default settings (no host). When starting the chip, having a USB voltage set with a power supply delivering 5.5V @ at max current 3.5A, I cannot get the charger to charge the batteries. 

When debugging a bit more my pins PG and stat are at 1 seems to mean that the USB voltage does not meet requirements but i am sure it does at 5.5V & 3.5A.

Do you foresee something wrong in my design below?

Thanks for helping.

Best regards
