How to Unplug USB 3.0 19pin Connectors from Mainboard
The USB 3.0 19-pin connector is a standard connector that is not designed for
multi-times plug/unplug usage. The purpose of the USB 3.0 19-pin connector is
to securely connect when the cable is plugged in, not to allow users to unplug
easily. Therefore, there are small tabs located on the cable connector that
clip into the pin header connector from the inside.
To pull off the USB 3.0 cable, DO NOT unplug the USB cable from the module directly, Wiggle Left- Right to release the small tabs from sockets then unplug the cable, refer to the below pictures for example:
