Hey there, I'm working off a Macbook 13", OSX 10.5.8. I recently made upgrades which have left me needing more USB ports. I just wanted to check before running out and buying one of these things that there aren't any issues I may run into or concerns I should have. I read somewhere that, with a macbook, a hub should only be added to the front built-in port(further from the screen). On an unrelated note, I have an firewire ipod cable that will charge my ipod but not show it in Itunes. Any answers/guesses?
