Re: usb port numbers

Mike, There is 1 black port, 1 blue port and 1 yellow port. All 3 of them are functioning usb ports.

Any idea why they made one port yellow?

Thanks for the info.

Hi Nancy,
Here's how  you can feel the difference using your finger between a USB 2.0 port, & a USB 3.0 port.
Stick the end of your finger into the USB port.  The 2.0 port will feel pretty open with the contact in, deeper, but the 3.0 port will feel like there are contacts right up to the edge of the opening.
Black USB ports are 2.0 and blue USB  ports are 3.0.

Take Care.  Mike.  Sent from my iBarstool.
