Yes, it is self powered. Belkin F5U307. Searching beforehand revealed there is compatability between this hub and MBP. Also, it is a 7 port hub, I have two other hubs (not active simultaneously when downloading pics), that are used to connect to iPhone and iPad, and they work fine for all purposes. I have also tried all of the other hub ports that are not tied up, and they also do not work when it comes to downloading pics from the camera (Canon 5D Mark 2).
Thanks for your help,
