Decided to try USB port yesterday... Wouldn't work. Was a thumb drive. Someone help.

Make sure that it is formatted FAT32. Also these things are picky about different brands of flash drives. I had a HP 16GB USB flash drive working great on my unit a while back but I lost the drive and now I'm having trouble finding another one. There used to be a post on this forum somewhere where everyone chimed in with what worked and what didn't. Personally, I am trying to get a San Disk 32GB Flash drive to work. It will work for a while and then starts kicking in and out. I will post back here if i find a modern drive that works. I fear that we are going to be stuck trying to find old drives to work on these units.
