I have the part not buy here, but that probably does not matter. Plugged into my computer, it was immediately recognized as a hub. A Terst with a USB stick, which is also recognized immediately, did not reveal any problems. Finally, I plugged my EOS20D, for which I have actually bought the cable, and then the camera is detected immediately. With the capture function from the EOS software out the camera can be smoothly controlled and she plays as smoothly the image files instantly on your computer. I can only say: Great part !!!!!!
