Programmable controlled computer switch

A programmable controlled computer switch capable of switching between a controlling function and a hub function for a console device and a universal serial bus device, comprising:

• a console port interface having console ports for connecting console devices, the console devices initially being with a controlling function;
• a universal serial bus (USB) hub port interface having USB hub ports for connecting USB devices, the USB devices initially being with a hub function;
• plural computer interfaces having a computer port respectively for connecting a computer device;
• a matrix switching circuit connected to the console port interface, the USB hub port interface and the plural computer interfaces;
• and
• a main controlling circuit connected between the matrix switching circuit and the plural computer interfaces, wherein the main controlling circuit maintains the controlling function of the console devices or switches the console devices to one having a hub function, and maintains the hub function of the USB devices or switches the USB devices to one having a controlling function,
• wherein the main controlling circuit transmits controlling signals of the devices having a controlling function to the plural computer interfaces through a bus, and selects at least one of the devices having a hub function to connect to one of the plural computer interfaces by means of the matrix switching circuit.
