I can't seem to transfer any mp4 files from my pc to the thrive through the mini usb cable. It starts to copy and the bar gets full, indicating it's almost done, and then there's an error saying the thrive stopped responding. I can transfer them file via a usb flash drive, but it's annoying to take the extra step. I read somewhere else that turning on USB Debugging would solve this, but when I do that the thrive is not recognized by the pc. Anyone have any info on this?
