I'm using a 2-port USB-C kvm to switch between a Dell laptop (or sometimes a Surface Go) and an Intel Switch to the 8th generation NUC. The laptop has USB-C and the NUC has Thunderbolt 3. Both work smoothly with the media keys on the keyboard and the additional mouse buttons working properly. USB PD pass-through works, but only with certain brands of USB-C chargers. Non-brands generally didn't negotiate power supplies and the Dell didn't charge when connected to a KVM, although it did work when connected directly to a laptop. The Surface Go has broader compatibility, but even that doesn't work with all USB-c chargers. The Anker and Ravpower chargers seemed to work correctly in every combination I tried. Another note about USB PD is that it is capped at 60W per device. This may or may not be an issue for you, so check your laptop's power requirements. Note that USB ports are 2.0 only due to limitations of the USB-c standard. You can use USB 3.x or 4k@60hz over USB-c, but not both - the current standard just doesn't have enough bandwidth for USB-c 3.1 gen2 (10Gbps). Only Thunderbolt currently can do both, and I don't know of any Thunderbolt KVM on the market. Since I prefer 4k@60Hz over USB 3, the switch works very well for my needs. I have connected half a dozen USB 2.0 devices via kvm and everything works without problems. There is only one major thing I would change about this kvm: I would increase the current the USB ports can deliver. This is probably a limitation of USB 2.0, so I use a powered hub instead. It doesn't matter much. On my wish list I would prefer if it was a 4 port switch and if I wanted to add keyboard hotkey switching. Otherwise it was almost perfect.
