According to other comments, I've tried this with several flash drives (256KB, 512KB, 8GB, 16GB) properly formatted as FAT32. The ready light is not flashing. No entry. Follow the instructions carefully. Nothing. Playback was of poor quality. I tried different tapes. Homemade or commercial cassettes sounded equally bad. Playback worked best with a USB port connected to a PC for power. The two AA batteries didn't work well and were very hot when I took them out. I am returning the unit after a very unfortunate few hours.
