Troubleshoot why all of a sudden the "Touchscreen" mode on the ACER Aspire R15 i7 computer hardware not working .
This happens after the software installation of INTEL 520 graphics driver for the ACER Aspire R15 i7 .
ANSWER
Go into "Device Manager" and then search for "Universal Serial Bus controllers" make sure that ALL the USB-related devices are ENABLED as shown here . After that the "Human Interface Devices" which is part of the "Device Manager" will show the presence of the "HID-complaint touch screen" as shown here . It seems to me that this happens simultaneously when ALL the USB-related devices are ENABLED in the "Universal Serial Bus controllers". As a result of that , now the "Touchscreen" mode of the ACER Aspire R15 i7 is working and the USB port of the ACER Aspire R15 i7 is also working , too.
