Hello all. I've got some problems with my USB wire that connects my Canon SD 450 to my MBP. lately, whenever i've connected it to my USB hub, it says it's been drawing too much power and has shut down. when i try to connect it by itself the wire does not work at all so i'm figuring the wire is faulty and am buying a replacement but am not sure what type to get.
