I recently purchased an Acer Aspire 5750Z and I have a question about how one of the USB Ports looks. On the right hand side of the laptop, the USB port to the right looks completely different than the other 2 USB ports on the laptop. When looking straight in to the port, the front of the USB connector has 4 small holes whereas the others ports are just perfectly flat and no holes are visible.
Please see the attached image to match my description.
I would greatly appreciate it if anyone could explain to me why this USB port looks different than the others.
