Upon booting again, I took a closer look at the verbose. It said something like "there is already a device assigned to input." I'm assuming it loaded the keyboard, but when it tried to subsequently load the mouse it ran into a device conflict. Even if the mouse and keyboard had their own dedicated USB ports, I doubt it would solve the problem.
A good effort, but it's not there yet.
