Apple introduced a dongle named the Camera connection kit along with the iPad back in April this year. This is a nifty accessory that lets users to connect their digital camera to the iPad in order to quickly import or browse images from a digital camera on the iPad.
As users who purchased the dongle have noted since then, the camera connection kit was also capable to connecting to other USB devices like the keyboards, microphones, etc. No longer. Users who have updated their iPad to the latest iOS 4.2 platform are reporting that the dongle is no longer capable of connecting the iPads to devices that consume more than 20mAh.
This limitation does not restrict the accessory’s original function that is to help users connect the iPad to a digital camera. But for those who were thinking of alternate use-cases, the dongle no longer seems to be a useful device.
