Electronic device and control method thereof

Abstract

An electronic device and its control method are disclosed. The electronic device includes a game processing unit, a built-in USB device, a customized service unit, and an I2C haptic touchpad. The game processing unit executes a game application. The built-in USB device is connected to the game processing unit. The built-in USB device includes a descriptor and a USB controller. The descriptor declares that the built-in USB device has a vibration function. The USB controller receives a gaming event trigger command from the game processing unit and then issues a customized HID output report. The customized service unit receives the customized HID output report and then issues a standard HID output report. The I2C haptic touchpad receives the standard HID output report and then vibrates.

Claims

1. An electronic device comprising: A game processing unit for executing a game application; A built-in USB device is connected to the game processing unit. The built-in USB device includes: a descriptor for declaring that the built-in USB device has a vibration function; a USB controller for receiving a gaming event trigger command from the game processing unit and issuing a customized HID output report; a customized service unit for receiving the customized HID output report and issuing a standard HID output report; and an I2C haptic touchpad for receiving the standard HID output report and vibrating, wherein the descriptor is different from the XUSB descriptor.

2. The electronic device as described in claim 1, wherein the descriptor includes a Usage Page or an output format.
