The listing, USB Cable has ended.
What you're getting -
One USB 2 cable.
This cable is a Type-A to Mini-B. The Type-A is perfect for your computer and the Mini-B will fit most devices other than cell phones, which normally take the Micro-B these days - unless it's an iPhone.
USB 2 is compatible with all USB technologies out there. If your computer or device is USB 1 or USB 3, this cable will still work. However, if you have USB 1, the connection speed will still be 1 and if you have USB 3, the connection speed with be 2, since the bottleneck will be the cable.
Hope that helps. If you have any questions, feel free to ask.
