I have a T100TA running Windows 8.1. While I was using Internet Explorer, I briefly saw a screen showing that the Asus USB Driver Bootloader was being installed, so I waited for the progress bar to complete. I was unable to find it using the Device Manager, but I'm not completely sure of the exact description. Where was it installed, and how is it used? Not very familiar with devices or hardware, so thanks for your response or suggestions for further research.
