This is a Pioneer USB-connected BD drive. I am selling it because I haven't used it for a long time. Only the main unit and the USB cable are included. The original accessories and the Y-shaped USB cable that can enhance the power supply are missing. It was working the last time I used it, but I forgot to check its operation before listing it, so I will do so later. When I used the USB cable in the image instead of the Y-shaped USB cable, without connecting an AC adapter, it worked, but there were cases where there was a lack of power during high-speed reading. I will add the missing accessories or an AC adapter later if I can find them.
