Boot camp doesn’t recognize USB for LG Ultrafine 4k I have an LG Ultrafine 4k display and whenever I try to run Bootcamp it eventually says device not recognized and it won’t work. It’s a new monitor, so not sure what the issue is. I have 2017 Macbokk Pro
Make sure these things work


displaying
charging for laptop
USB expansion ports
brightness adjustment (in BootCamp control panel)
speaker


Then nothing more could be expected from this display. The error might due to no driver for the ambient light sensor (macOS doesn't utilize it either).
