Here's an oddity after install of the USB Hub: 
  
Hub has been working great, used Carplay a few times already.  I wanted to see if I was able to have my iPod hooked up/playing while having Carplay also in use.  I had one OEM Lightning cable and one after market in my car so I tested with those.  I couldn't get Carplay to register from the after market, so Carplay was working with the OEM.  Carplay was on, but then couldn't get the iPod to register at all.  I unplugged both, restarted my phone.  Now neither cable will register either iPhone or iPod or charge or load up Carplay. 
  
I was wondering if anyone had any similar experiences.  I'm going to go out there with another OEM cable, with a fresh reboot of phone and car and see if anything changes.
