I want to add some more USB ports to my system. The two that came with the system are both being used, one for my printer and the other for my digital camera. I do not want an external hub. Too many cables makes a mess. So I guess that brings me to two choices. I can add a PCI USB port card or I have seen ports that mount in a drive bay thereby giving you front of the case access. My question is...how do these drive bay USB ports connect to my system? They say the power is from the floppy drive power connection. But how does it connect to the USB? Would it plug into one of my existing USB ports? If so, that could be messy looking as well. Does anyone know?
