USB Connector Compatibility Chart Use the USB physical compatibility chart below to see which USB plug (male connector) is compatible with which USB receptacle (female connector). Some connectors changed from USB version to USB version, so be sure to use the correct one at either end. For example, using the chart below, you can see that USB 3.0 Type B plugs fit only in USB 3.0 Type B receptacles. You can also see that USB 2.0 Micro-A plugs fit in both USB 3.0 Micro-AB and USB 2.0 Micro-AB receptacles. The below USB compatibility chart was designed with physical compatibility in mind only. In most cases, this also means that devices will communicate properly, albeit at the lowest common speed, but it's no guarantee. The biggest issue you'll probably find is that some USB 3.0 devices may not communicate at all when used on a computer or other host device that supports only USB 1.1.
