Is there a certain format/process that should be used for the system to recognize the a USB stick w/ media? I have a Lexar 32GB (USB 3/FAT32) that is readable just fine. I'm trying a PNY 64GB (USB 2/FAT32&EXFAT format) that can't be read. I looked at the manual and it said USB 2 is supported but I'm wondering if that's no longer true w/ updated Sensus updates? If you're using a stick that size or larger you mind sharing any tips? TIA.
