I am having some problems with the USB identification feature.

I would like to work without it, and to make sure that regardless of which type of charger (USB or adaptor) is connected, the charging current will be 0.54A

How can I cancel the USB identification?

Take a look at the BQ24040, it can be configured with ISET to program the current and ISET2 low. This will fix the current at desired value.

Hi Bill,

Can you send a diagram?
I couldn't find that configuration at the datasheet
