   Got a new Samsung phone with a USB Type-C port. That happily connects to   
   both my main workstation and my laptop, and will accept charging from   
   both. I tried a Type-A-to-Type-C cable for the former, and a Type-C-to-   
   Type-C cable on both, and everything worked fine. I have also successfully   
   done data transfers on the workstation -- didn’t actually try the laptop   
   yet, but I imagine that will work too.   
      
   I have this old power adapter brick (says it’s “Asus” brand) with a USB   
   Type-A port on its back. I was able to use that to charge my old phone   
   with a Micro-USB connector (yeah, that old) and suitable cable, but the   
   new phone will not accept any power from it via a Type-A-to-Type-C cable.   
      
   As far as I know, that adapter is completely dumb, knows nothing of “USB-   
   PD” or any such, so it should just be putting out 5V through the power   
   pins and that’s it. Says it’s rated for 2A. But the new phone doesn’t   
   want   
   to look at that.   
      
   Any thoughts on what might be going wrong? Not enough current, perhaps?   
      
   Thanks for any suggestions.
