Solution: You'll need a new PC. Or at least a new USB3 card. I wish I could say exactly what the issue is. But not 100% sure. I'm leaning toward the USB ports. I'm a software expert, so hopefully some hardware expert can expound on exactly what's different between my desktop vs. laptop. No issues at all getting multiple webcams, even if they're identical, to work on my laptop. Also note that my laptop is newer and more powerful than my desktop.
