*edit* I am referring to a barcode scanner Let me start by saying that I have only tried this with a couple USB scanners, but I think they are pretty much all standardized, so this should work for all of you. When I first saw the Camera Connector kits for the iPad and noticed it had a USB port, I was excited about future USB support. Then I heard that USB keyboard will work with the connector kit. And since a USB scanner is basically a USB keyboard, I though for sure all I would have to do was plug it in and BOOM! Sadly, I was disappointed and wrong. BUT! Thank goodness my iPad is jailbroken! I remember there being a jailbroken app called "re-supported" that allows old video and audio output devices to work on the new generation devices. I took a shot in the dark and paid the dollar or two for the app. To my surprise, the USB scanner now works!! You still get an error message when you plug it in saying "this device is not supported" but you can close the message and you are on your way! So, in closing: Jailbroken iPad + "Resupported" + USB Scanner = Success! Let me know if you guys have tried this or if it is helpful to you!
