My iPhone is not connecting to my PowerBook when it is plugged directly into the USB port. My PB supports USB 2.0 and it has worked fine when connected via my powered USB hub. It seems like my PB doesn't have enough juice to support the iPhone without going through a powered hub. Has anyone experienced this themselves and/or know of a fix.

17" Aluminum PB 1.67GHz, Mac OS X (10.5.1), MacBook, iMac, iPhone, iPods, AirPort Extreme and Apple TV

This is actually one of the reasons that I wish Apple had left support for Firewire in the new iPod related devices (sync support I mean...it still works for power). USB power is less than firewire which always seems to provide enough juice to charge. I actually saved the firewire dock cable from an older iPod that I had and I use it to charge my iPhone from my Powerbook when I'm out of town (it can even charge when the powerbook is asleep, unlike the USB port). This also saves me having to bring along the iPhone charger...the firewire cable is tiny and fits in my small laptop bag nicely.

    I am having the same intermittent problem. It doesn't always want to charge off the port of my computer when connected. I power cycled my iphone and still, nada. once i get in the red and unplug and reconnect, then it will start to charge.

    Ya I've seen another posting from someone saying if their phone got into the red it would then charge. The problem is I try to avoid the red. I have found if I just connect the iPhone that at some point (maybe an hour or two) it does seem to recognize the PowerBook and charge. I can then launch iTunes and do a sync. Someone also suggested resetting the computer's PMU which didn't make a difference.

    Fortunately I will be back in my home office after the weekend and will be able to connect my iPhone via a powered USB hub which works fine.

    That's good to know. I never thought about using a F/W cable. As long as it's safe and won't damage my iPhone I might try it. Does it also transfer data faster too?
