To solve the issue of finger print i have installed the following for windows 7 64 bit
These updates made the FPrint works .
Regarding the Unknown stuff in the Device Manager installed
I upgraded to Windows 10 on my XT3. Is there a Control Point driver? If not, is there a known earlier version (e.g. Win 8 64 bit) that will work. My buttons on the tablet face stopped working and my stylus is not longer recognized. What links are the recommended driver updates after updating to Win 10 64 bit (clean install) since the XT3 is no longer supported. I updated all drivers per the auto detect at dell.com (BIOS, Network, SATA, Chipset) downloaded system manager, but still can't get buttons and stylus to work. After I am done with that I will figure out how to get the finger print reader to work.
