I have the Asus Vivobook X202E as well, and I was able to install the latest clover quite effortlessly. My setup right now with Yosemite is actually the closest I have come to get everything working, quite a bit better than my initial installation with Mountain Lion.
Right now I have working:
Asus FN Keys- All work except the brightness up and brightness down.
Sleep and wake- work great, no restarts, wake is pretty fast.
Trim is enabled, on my SSD.
Intel HD 4000 Graphics are fully working.
Native Brightness is working great.
Built-in camera works great.
Start up is quick.
Trackpad is good/ works fully, not great, as far as glitchiness it is very low compared to other builds.
Touch Screen works out of box.
I'm thinking my USB 3.0 is working, all my USB ports are active and working.
Audio works pretty well, not very loud though. Loud enough I guess.
Not working-
Bluetooth, but I don't ever use it, so I just locked it in the bios.
Like I said the Asus FN Keys for brightness up and down aren't working, but that's not a big deal.
As others mentioned though, I would like to disable the touchscreen on my Asus X202E, but I'm not sure how to go about it? Is there a kext I could just delete that controls the human interface device (HID) for the touchscreen, or do I need to disable it somehow? Any info would be greatly appreciated.
Thanks in advance,
