So I got this 3.5 inch HDD enclosure from my school, on the back there is a usb port (printer type) and a ps2 port. I'm guessing the USB port is for data and the ps2 port is for power. I tried looking this thing up but I couldn't find a single thing about it, so I tried plugging the usb and the ps2 port, the only thing connect to the ps2 port is vcc and ground. But only the 'USB light' lights up.
Here are some pictures I took:
