A system for operating an accessory device in a terminal, the system comprising:
- the terminal including a Universal Serial Bus (USB) port and an ear jack port;
- and
- the accessory device simultaneously connecting with the USB port and the ear jack port of the terminal, and transferring a signal corresponding to a key input signal to the terminal through the USB port and the ear jack port.
A method of operating an accessory device in a terminal, the method comprising:
- connecting a Universal Serial Bus (USB) connector and an ear jack connector of the accessory device with a USB port and an ear jack port of the terminal, respectively;
- transferring a signal from the accessory device to the terminal through the USB port and the ear jack port, the signal corresponding to a key input signal received by the accessory device;
- and
- differentiating, by the terminal, the key input signal of the accessory device based on the signal transferred through the USB port and the ear jack port.
A terminal for supporting an operation of an accessory device, the terminal comprising:
- a Universal Serial Bus (USB) port;
- an ear jack port;
- and
- a controller for differentiating a key input signal of the accessory device based on at least one of resistance variation, voltage variation, and current variation detected via the USB port and the ear jack port when the accessory device simultaneously connects with the USB port and the ear jack port.
