Abstract: An adaptor device including a first interface, a second interface, a negotiation circuit and a type C manager and controller is provided. The first interface is a universal serial bus (USB) 2.0 interface, and the second interface is a type C USB interface. When the first interface receives a first mode swap request, the type C manager and controller transmits a first mode swap signal in a type C format through the second interface according to the first mode swap request; when the second interface receives a second mode swap request, the negotiation circuit transmits a second mode swap signal in a USB 2.0 format through the first interface according to the second mode swap request.
