• iOS 4.2 Reduces Power Output to iPad Camera Connection Kit

    iPad owners who recently upgraded to iOS 4.2 are in for a shock if they use the iPad Camera Connection Kit with certain cameras. With the iOS 4.2 update, Apple has lowered the power output of the iPad’s 30-pin connector to a mere 20mA, down from 100mA in iOS 3.2. This means that some cameras and other peripherals that use the 30-pin connector, will not function if they try to draw too much power from the iPad. If you do attempt to use a power-hungry device you will get the following message: “The connected USB device requires too much power.”

    The new power specification is most likely a new feature designed to improve battery life on the iPad. This is little comfort to iPad owners, however, as some users rely on their devices on a daily basis. Hopefully, this is just a bug that will be addressed in the next iOS update, rumored to be coming later this month. Currently, even Apple’s own USB keyboard does not function under iOS 4.2. Other affected devices include USB flash drives and USB powered microphones. Self-powered devices, however, remain unaffected.

    The ability to upload pictures on the go, is one of the iPad’s nicer features. For now, photographers who want to upload pictures directly to their iPad, should wait and see if their equipment is compatible with the latest iOS update. Unfortunately, downgrading to pervious iOS versions is something Apple frowns upon, so some users may end up being stuck until this problem is resolved.
