Dell Inspiron 15 7000 :: No Driver Is Available For The Keyboard / Touchpad Of Laptop

As the title says, there is no driver available for the keyboard/touchpad on this laptop. There is no way to adjust the current touchpad settings. I've followed all the troubleshooting steps for Windows 8.1, but this model simply lacks a Dell Touchpad interface or any settings to change gestures or scrolling speeds and sensitivity. None of the usual gestures even work, not even pinch-zoom.

This wouldn't be a big deal if there were a driver available to fix the issue, but there isn't - this model does not have a input driver available at all. All that is provided is an ancient Mouse Properties thing that seems designed for a wired mouse and some ETDWare SmartTouch thing that does nothing at all as far as I can tell. The literature for this model claims that the laptop has " a roomy, gesture-enabled precision touchpad, [which can] zoom, click and point with impressive accuracy and speed." Well the gestures consist of two finger scrolling and nothing else, and there is no zoom, not to mention any other gestures, and accuracy and speed tend to rely on users tweaking things to their own unique preferences (impossible as it is).

All this is to say, is Dell working on getting an input driver for this model? Is there an update in the works? Is there some other method available to remedy this unfortunate failing of an otherwise pretty nice machine? If I don't hear back in a week or so, I'm just going to return this and buy a different brand.
