So I have this AEK II that I want to mod to a Teensy with TMK's firmware and run off USB. However, I want to keep the pass through open that is on the other side of the keyboard. Those of you that aren't familiar with this keyboard there is a port on the left side that connects the keyboard to the computer and then there is another port on the right side to plug in the mouse. I want to keep this functionality. I already have contacted Pexon and he can and will make me a pair of cables so I can keep everything looking stock.
My question now is, in order to wire this up can I just splice into the wires between the left connector and the teensy to connect the right connector or do I need to add in a USB hub?
