iPad with USB keyboard!

Once again you can use your iPad with a full USB keyboard. (My old video is here.)
You need an Apple USB adapter of course, but here's the new thing: you simply plug in an Unpowered USB hub between the iPad and the keyboard.
For example the excellent keyboard on the Alphasmart Neo can be used.

Just ignore the "device not supported" message the iPad gives you.
(I've not tested if this works with the new Lightning connectors on iPad 4 and Mini. You need a different Apple adapter for them of course.)
