[QUOTE="hughvane, post: 834695, member: 56231"] I remember reading in other forums about using a USB 'splitter' (my terminology) in order to harness the power from two USB hubs for an external device that has high demand. I'm puzzled, in fact intrigued, to read that the use of a powered hub prevents use of your external device. To the best of my knowledge, using a hub doesn't significantly change anything in terms of interconnectivity. We learn something new every day :). Yes, USB power on Macs is an old and recurrent issue, which is why some people stay with a Windows machine in addition to their Macs. I don't think the use of Win XP via Bootcamp will change the USB power issue, as it's hardware - not software - related. I'm going to suggest that you post your USB power issue on [url=http://forums.macosxhints.com/]The macosxhints Forums - For discussing everything OS X...[/url] where there are some seriously knowledgeable people who may be able better to explain WHY the USB port 1 works where others don't, and to suggest a fix or a workaround.
