16-seater USB hub
As usual, all the weirdest USB devices are named after the Japanese, in this case it is no different.
The Century USB hub has 16 USB 2.0 slots, shared by these two computers, meaning that 8-8 USB devices per person can be connected to the device running from a separate power source. Unfortunately, it can only serve one machine at a time, in which case we can switch between computers with a single switch.
