I’ve been burned from this before so I want to make sure that if I bought a FW13 with a USB-C module that I could connect this to my USB-C monitor hub and then the connected FW port will handle charging, display signal out, and peripheral up/downstream? Realistically I’ll be connecting just KVM to this single port but it being able to supply power to the laptop at the same time would be really nice.
I expect to be connecting other devices to their own dedicated USB ports (Arduino for example)
Yes, as long as the hub supports USB-PD charging, which most should.
