A media sharing device includes a data bridge device and two switching control modules. The data bridge device has two terminals connected to USB interface ports of two computers and provides bi-directional transmission of media of displayed image, keyboard, cursor, and sound of the computers in USB data format between the computers. Switching control modules are mounted in the computers and are activated by an associated activation device to switch the controlling side and controlled side of the computers. The controlling side computer transmits data of displayed image, keyboard, cursor, and sound to the controlled side computer for computer display, executing the displayed image, keyboard, cursor, and sound supplied from the controlling side computer, or the activation device of the controlled side computer is activated to issue an instruction to the controlling side computer to switch the controlling side and the controlled side of the computers.

A system and method for synchronized operation of touch device has a mobile touch device which includes a USB transmission interface and a touch screen and an electronic facility host. The USB transmission interface connects to the USB interface of the electronic facility host and synchronizes image displaying, synchronized keyboard operation, and cursor operation so an image of the touch screen of the mobile touch device synchronously opens an image displaying zone on the display device of the electronic facility host and the keyboard and the cursor device directly simulate and synchronously operate touch display operation functions of the mobile touch device in the image displaying zone, operation of file duplication, writing, deletion, and edition between the facility host and the mobile touch device with at least one window of the operation platform of the electronic facility host.

A USB-to-VGA converter includes a USB controller connectable to a USB port of a computer for receiving USB based display signals from the computer, a VGA controller connectable to a display device for conveying VGA signals to the display device and a bridge connected between the USB controller and the VGA controller. The bridge receives a bus control command from the USB controller and issues a first-in-first-out control signal to the USB controller to receive the USB based display signals from the USB controller in a first-in-first-out manner. The bridge circuit converts the USB based display signals into corresponding VGA signals and forwarding the VGA signals to the VGA controller, which in turn applies the VGA signals to the display device. No display interface card is required inside the host computer for generation of the VGA signals.
