I know this topic has been aired before, and I've followed all the advice offered to no avail. To summarise, I've connected my tablet to this computer before successfully, and uploaded pictures onto the pc. However, it won't do it now. The pc sees it as a device, and swapping between the two usb modes on the tablet produces a reaction from the pc, but I can't find it anywhere on the pc in order to do any work. I'm not sure if android was updated after the last time I used it- i'm on 4.4.4 at the moment.
