I'm amazed to find a thread this recent on this. A friend just acquired a Canon 5501 and can't get it to work. It sounds like the drive is never getting selected by the system. He claims there are no jumpers on it. I find that a little hard to believe, especially since I found a couple of much older articles referring to jumpers. I'm too remote to look for myself, so can one of you who has seen one either confirm this or tell me where to find the jumpers?
