Hello I have an Ipad. It use to open file explorer when I plugged it in. I messed up and set it to "do nothing". Now it won't see it at all, and my virtual box can't see it either. Where is the setting so I can change it back to ask? I went to settings>detail, but I didn't see it in removable devices. Any help would be great. I'm on 12.10 Ubuntu.
