    OK, so I was trying to split a USB cable so that my keyboard could give input to two things at the same time. Here's what I did: I had a spare USB hub and I plugged the keyboard into it. I then took 2 USB male connectors and hooked them up the output of the hub. I first tried to have only one of the +5V and ground hooked up, but it didn't work. I had to hook up power and ground on both usb heads. Can anyone tell me what I'm doing wrong?

    In case I lost you here's a small diagram

    BTW: It didn't work with both devices. However it DID work on one computer, but not the other. It's not the connections, because I unplugged the cable from the computer it was working on and it started working on the other computer. I probably did something blatantly obvious wrong. Can anyone point me in the right direction?

    I ditched the idea. It may be possible with some added components, but it definitely won't work by just splitting the cable. The digital signal will get all messed up and only one device will be working (at best).
