I am making a KVM switch for a single USB port. I found a tutorial for this online, but I am concerned if there is any problem with hooking up VCC like this. Is that alright?

No, it is not OK to connect two power supplies like that. Worst thing could be anything like frying two computers, maybe only USB port on motherboard.
