Connector1: USB 3.0 Front Panel Socket to USB 3.1 Front Panel Header.
Connector2: USB 3.0 Front Panel Header to USB3.0 Type-A connector.
The adapter is a converter to convert the available USB 3.0 header of a motherboard into a USB 3.1 header.
Thus the USB 3.1 port of a housing can also be supplied with USB 3.1 without a suitable mainboard.
The compact adapter can be inserted directly and requires no additional attachments.
