   Hi Carlos,   
      
   To help out, I went to my old logs and this is what mine was set to:   
     USB default settings

   I have to admit, I've always turned Developer Options on as one of the very   
   first things I do on any phone, but its "organization" is really messy.

   Mine does both charging & file transfer at the same time as far as I know.

   There are a ton of options in Developer Options.   
     Settings > Developer options   
     Useful devoptions switches   
     More devoptions switches   
     Even more devoptions switches   
      
   Probably some of the most useful (besides USB Debugging) are the   
   ability to randomize the MAC upon every connection (not just every AP).
