USB 2 HD connects to USB3 port question


Apr 25, 2013
I have a new Lenovo G500 i-3110 CPU, it came with 1 USB2 + 2 USB 3 ports, I'm using USB 2 port for my mouse and would like to use the USB 3 port for my USB 2 HD, I've read that USB 3 is backward compatible with USB 2, but what about the cable? I can still use the same USB 2 cable to connect to USB 3 port in my laptop or I have to purchase an adapter or new cable? I tried to insert the USB 2 cable and it won't fit in and I'm afraid to force it and damage the port.
