I've bought the cable to - to load the Archos 405 PC-independent - in conjunction with a small power supply. This works well. I had read somewhere that it is faster to this connector when. Via the mini USB port on the device After personal preferences but this is not so. Nevertheless, I would highly recommend this product because it works without restriction - even in data transfer. It's just not as universally applicable because of the special connection as a pure USB / mini-USB cable. That's why only 4 stars.
