What im trying to do is use one USB keyboard and one USB mouse to control 2 computers. Right! I should get a KVM, but the computers each have there own screen. I need a fast way to switch between using my Mac and PC on one keyboard and one mouse. Imput: 2 flat USB or some kind of adapter to make it into one. Maybe a 2 port usb hub to 2 port USB switch??? BUT! Then you run into USB power problems right? So the hubs would need DC power not run off USB power alone. Output: 2 USB cables to go to each comp. Thanks for your help. I spent ALL of today looking for comp tables w/ 2 keyboard trays, when I came up with this idea. So If i can do something like above, it will determine a lot of things maybe even if I get a new computer... Thanks Again!!!
