I have a Sony MZ-N505 MiniDisc player, with a Mini-USB connection port on the side, and my computer simply will not see it, as in it simply doesn't show up on the system. I have SonicStage installed, I have the drivers ready to go, but I can't for the life of me get my computer even recognize that I've connected it to the USB port. For reference, I'm using a Dell laptop with 8 gigs of RAM, an AMD A6 chip, and integrated graphics. I've tried to connect to all three USB ports, included the USB 3.0 port, but I've had no luck. Any suggestions?
