Don't know why they don't put it on their website as a download. Xerox worked with Microsoft to create a patch called win10_rs4_patch_220618 which Xerox technical support can send you. Turns out Microsoft did an update #1803 in early May, 2018 which somehow broke the ability to use the scanner via USB cable if your computer is using Windows 10. Updated: I contacted Xerox technical support.
