Try having just the blue fury plugged in. Before you start the program press the rst button near the USB port. Wait for it to go dark red and then press start on bitminter.
Ok, I tried this a few times, but unfortunately it doesn't seem to make any difference.
Are you still having issues? Try unplugging the blue fury and plugging it back in. Sometimes the RST button doesn't fix the problem for me, but "replugging" works.
