It'll never work. Sorry.
USB and other 'chainable' interfaces rely on polling to get the job done - one can connect 127 devices to a single USB port, but one also needs polling circuitry to call each device in series to keep the port from getting confused.
Consider it like an intersection with a stop light. The light goes red, the other traffic moves. then it switches. What you are doing is setting up an intersection with no light, which, as you could imagine, results in data smashing together and going nowhere.
to complicate matters further, USB port powered devices try to claim the port as their own, and will deny any intrusion from anything else, So, if you plug a passive device into a USB port, and a cellphone that can be charged via USB into your split-cable, the cellphone will win every time.
