I didn't know that this was a tablet that we were dealing with until you mentioned it. Found your tablet here.
I have never ran a linux OS on a tablet before, so I have 0 experience. I believe @Aravisian does have experience running a Linux OS on a tablet.
At least we have some info now on the system you are trying to work with. Seems your tablet came with Windows 8.1 originally.
EDIT: I found that other's have run into the same issue that you have. It seems there are no Linux drivers available to support the Intel AVStream Camera. Seems Intel created it souly for Windows, sad.
