I have put a new ASUS P8P67 Pro Motherboard in Dell XPS case, and it has one issue I so need to fix. I run two Keyboards on my Computer, a regular Keyboard and a Video Editing Keyboard. The regular Keyboard uses USB, but my Video Editing Keyboard uses a PS/2 keyboard/mouse port, the round one. Now the ASUS Motherboard has no mouse or Keyboard ports on the back of the board. So what I need is a connector to plug the PS/2 keyboard/mouse port into a USB port. Does such a device exist?
