I am new to android and was swayed to the Thrive because of the full USB capability over ANY other tablet. Having said that, the only thing that I have that actually works with the USB on the thrive is my thumb drive. Neither my external portable hard drive which houses my 400GB music and video collection nor my portable DVD player work through when plugged in to the USB port. I get an error message that says there is no USB device connected. My question is simply is there a way to get the tablet to recognize either device or am I limited to the 64GB of combined SD and internal memory plus my thumb drive?
