U4919DW, KVM, share USB camera to multiple PCs?

@Dimitrius  The display can be connected via USB to two separate PCs, which allows the USB ports built into the display to be used with either of those PCs.  Page 38 of the manual here addresses how to set up the cabling, and then Page 54 covers the USB Select Switch item that allow you to choose which PC should control the USB port at any given time based on which video input is selected.  So connect your camera to any USB port on the display, then connect USB cables from the display to each of your PCs and set up USB Select Switch as appropriate based on the video inputs you're using with each PC.
