USB 3 or USB 2

Hi has anyone gotten a USB 3.0 flash drive to work with the USB connector in a 2010 TL? I have tried 2 different flash drives (both USB 3.0) and both show no files on the drive. They both show all of the files on the computer.

I am going to try a 32 GB USB 2.0 flash drive tomorrow.

Cheers.
