I had this problem with a PNY 128 gig USB 3.
It worked fine on my computer, but the BDP-2 didn't see it, no matter what i did.
So then i ran the disk utility on the bdp-2. It showed the PNY, but the PNY actually had 4 partitions.
I then ran the erase from the disk utility. It wiped the drive and it created just 1 partition.
After that the BDP-2 could see it, and I could also move files to it from my computer.
I found the disk utility worked better on Internet explorer, as opposed to Firefox.
