For OSX Mac users, a note: if you use a portable, as I do, both old and new libusb libraries try to get info out of suspended USB devices like the camera. This adds many seconds of delay before the download starts. I edited the darwin_usb.c file in libusb.1.0, and essentially commented out code. This resulted in a much much faster download.
