Keychron C3 Pro not working with HID

So as I noted in another video I was having issues that a Razer Huntsman V2 TKL was not working with the HID port of the KVM.

I decided to take a shot with Keychron, have heard good things and wanted to give it a try. Same issue, when using an HID port on the KVM the keyboard does not function. Works fine on the USB 3 port.

To date I have only been able to get Logitech keyboards to work on the HID? Are there others that work and have decent macro software?

Not working at all? Or not working with KVM hotkeys?

To clarify, sorry if you’ve answered this somewhere, have you disabled n-key rollover? QMK can fix most of the issues people have:
