The side of my HP Elitebook 840 G2 has two USB ports. The users' guide states that they are both USB 3.0 ports and no information is offered to suggest they are different from each other, yet there is a physical difference.
The port on the left will accept a USB device. I am unable to plug a USB device into the USB port on the right. I looked at Wikipedia's diagrams for USB ports but did not locate a diagram that matches the port on the right.
How can I use the port on the right?
