Re: AcuEdit question
The Lightning-to-Camera adapter doesn't really allow you to use a connected USB stick. You need a USB stick with dual connectors, which are about the same price or less:
I have this one, though I don't much like it. The weird bend makes it difficult to connect.
I also have one similar to this. You slide the connector you need out, which retracts the one you're not using. The downside is when you plug it in there is not enough "catch" to keep the connector from sliding back in.
