Charge the iPad with the Camera Kit connected

[tagyro]

My problem:
I have to connect a usb barcode reader to the iPad thru the Camera Kit (no, I can't use a bluetooth one) and, at the same time, charge the iPad.
The iPad will be used in a store as a price checker and fixed in a box, so disconnecting the CameraKit to recharge the iPad is not an option.

I'm using an ipad data cable between the iPad and the Camera Kit (even though the cable only has 16 of the 30 pins connected). From the cable I've taken out a usb cable that plugs in the original ipad charger and the iPad recharges. But as soon as I attach the camera kit at the other end the iPad shows the NOT CHARGING message - and it doesn't charge, not even in sleep mode.

Take a look at the attachment to get a better idea.

Perhaps an iPad is not the best device for you now...that diagram is headache inducing! I cant imagine this is what Steve envisioned its uses for! If you charged it completely overnight, wouldn't the battery get you through the day?Or perhaps invest in another ipad and swap it out during the day..or enjoy your iPad at home, and bring the Macbook Pro in for this job! Sorry I cant help more! :(

This device: here (http://us.kensington.com/html/11205.html) has a USB pass through charger perhaps it may work.

You could try this: http://www.cablejive.com/products/duaLink.html

Attach one dock to iPad, plug in the camera connector to the other dock, and the USB to power source. No idea if it'll work, though.

EDIT: the dual link is not good for what I need.

The Kingston 4-in-1 would be good but it's discontinued and nowhere to be found.

Anyway, I've built my own ipad male-female data cable and nothing.
Now I'm trying to open the camera kit and connect directly on the pcb inside it.

As I've been told a few times already the iPad cannot be charged with the camera kit connected.

It has to do with the fact that the data+ and data- cables from the usb must send data to start the charging process.

Not entirely true. D+ D- are connected to a specific voltage to begin charging.

I'm hoping this works. We want to charge an iPad while having a desktop magnetic card reader attached. We also already found a small usb hub with an on/off switch so the reader can be enabled/disabled to allow onscreen keyboard use.
