You might have to install the full chipset drivers, thats what I had to do on my netbook to get everything working, try to find out what the chipset is, and hopefully that will solve your problems.
As far as I can tell, all of the hardware is working now. I only had this a day before I wiped the drive with Win8. The fingerprint reader is working now, the touch mouse is working, including the scroll function, and I can tether my Droid X for mobile internet access.
