DA9053 USB charging - by alternative 5V source

Hello

I'd like to use the VBUS input to charge the main battery from a 5V source that isn't USB compliant ( DC_IN is already committed) at a charge rate of at least 1A. This 5V source does not have the D+, D- connections and therefore the DA9053 cannot automatically determine the source's capability. Will the DA9053 allow charging from VBUS at arbitrary charging rate if the D+, D- inputs are unconnected ? Or, perhaps, is there a way of tieing these inputs to make the DA9053 allow it?

This question does not seem to be addressed by the two App notes PM-006, PM-073 I was referred to before.

Many thanks

Jeremy
