I found out an interesting fact at the dealer today. One of the issues I told them when I dropped it off was that I couldn't get my USB sticks to read in the USB hub. My wireless carplay works fine. I plugged in my wife's iphone since her phone isn't paired and it read her phone just fine. I tried 4 different USB drives and they all reported "device error". I left all the USB drives in the truck and the tech checked them out. He said that they are all formatted incorrectly (including the one I used to use in 2015 Charger R/T and the one in my wife's 2017 Pacifica). It turns out that the sticks need to be formatted as FAT32 and the USB drives I had were formatted as exFAT. I reformatted the one I want to use for my music, reloaded it, and it works. So, bottom line, if you have a USB drive that isn't reading in your truck, check the formatting and see if that's the issue.
