Abstract: A driving device for an expansion card, a driving method thereof and a motherboard are provided. The driving method includes the step of detecting the information of an expansion card. When the information indicates that the expansion card is a nonstandard interface expansion card, a switch is turned on, and a chip unit drives the nonstandard interface expansion card via the switch. When the information indicates that the expansion card is a standard interface expansion card, the switch is turned off, and the chip unit drives the standard interface expansion card.

Abstract: An electronic device comprising a circuit board, a first connector, at least a signal wire and an adapter is provided. The first connector is disposed on the circuit board. The signal wire has a second connector. The adapter is used for connecting the first and the second connectors. The adapter includes a base and multiple guiding signs. The base has a first connecting portion and a second connecting portion. The first connecting portion is suitable for connecting with the first connector while the second connecting portion is suitable for connecting with the second connector. In addition, the guiding signs are located on the surface of the base. The electronic device is easy for assembly through the adapter.
