I purchased an app called DSLR controller and it was incredible. It enabled me to control my camera like a DREAM, and is in fact why I purchased this tablet. Now, the app no longer recognizes a DSLR camera is connected. I know the app still works, the cable is good and my Samsung dongle works. I've tried other apps that are specific to this tablet and my DSLR with the same results. I've also tried different cables and dongles as well. No damage has been done to the tablet so it's got to be a software or firmware issue. I even did a total wipe and factory reset. Did Samsung do something in the latest update to kill this functionality with the USB port? If so, how can I recover that? I bought this tab specifically to help in my work (as a photographer) and now it's no longer useful in that capacity. Please help!!!!
