We have a problem with OTG mode of BQ25892. All features of chip are working correctly beside the fact that we are unable to set OTG_CONFIG bit while chip is power supplied via VBUS.

Problem only exists while charger is power supplied over VBUS, after having VBUS disconnected we are able to set correctly OTG_CONFIG and it keeps it's correct state even after VBUS power returns. After having it set to 0 we are unable to set it again while VBUS is present.
Problem seems to be the same as:
