    (No reply under general, so I thought I'd ask the same question in the hacking forum.)

    Can someone with an iPad running iOS 4.21 and the camera connection kit please test if you can connect a USB keyboard and type in a text field? This has been unofficially supported in previous iOS versions and I want to make sure it still works before I upgrade.

    (Note: You will probably see a "this device is unsupported" mesg upon plugging in. Just click OK and then you should then be able to type. USB keyboards with built-in hubs or extra non-standard buttons might not work.)

    Thanks,
    Jeff

    USB Keyboard Works

    Just tested it and it works OK, just like you said it displayed the unsupported device message, I disregarded and went into Notes and typed on with no issues. I use the BT apple keyboard and that worked good also after upgrade.

    Apple reduced the maximum power which the USB device can withdraw to 20ma from 100ma in ios 4.2. And here is the problemen with most USB devices which need more.

    You now need an seperated powered USB hub as an workaround or try another USB keyboard.

    Haha. If that is true, its just more evidence of why I dislike Apple as a company. They figure out that their accessories only need X amount of power and "upgrade" the OS so that only their accessories and the few non Apple accessories that fit within their parameters work.

    Thank GOD that Apple's marketshare on phones is shrinking and that their marketshare on computers remains low. It would be a disaster if this type of behavior became standard for the industry.
