Trying to find out why some USB thumb drives cannot be read by SYNC 3. Have a 2016 Edge Titanium with the updated (Apple CarPlay capable) media hub. Have used a Lexar 3.0 drive with no problem (formatted with either ExFat or Fat32) but some newer SanDisk 3.0 drives and a Samsung 3.1 drive will not be recognized when formatted either way. Get a notification saying "error, bad cable or chan...." (note is cut off and doesn't scroll). Have erased and reformatted several times, but won't work. The drives are easily read by my Mac and by the USB ports in a new GMC Terrain. Am pulling my hair out (what little I have left) trying to figure out why. Anyone experience these same problems?
