HELP - I posted earlier that the USB option worked. It did, but only in some computers and some USB ports. It works well on my laptop when I use the USB ports on my docking bay. However, when I try to use it in the USB ports on the laptop itself, it does not even detect it. I have tried both ports many times. One time, XP reported that the USB device that I plugged in malfunctioned. I have also tried it in my home computer that regularly has USB devices plugged in. I even unplugged all USB devices because I thought that it might be a power issue. Speaking of power, do you think that the USB port is unpowered on my computers? I bought a new motherboard specifically for the MAME I am building, but the power supply that I was going to use is not the right type, so I have been unable to test the minipac on its future motherboard mate. I have purchased another power supply as well as a USB externally power hub in order to test with the new motherboard as well as a powered hub. Any ideas would be greatly appreciated.
