Abstract
An extension device for connecting one or more peripheral devices to a computer, comprising a first bus for connecting to the computer; a second bus for connecting to the computer; a hub coupled to the first bus for connecting the computer to one or more peripheral devices; a controller for connecting the computer to a high-bandwidth device, the controller being switchably coupled to the hub and the second bus; and a switch for switching the controller, from being coupled to the hub, to being coupled to the second bus, when a connection to the computer is detected on the second bus.
Claims12
An extension device for connecting one or more peripheral devices to a computer, comprising:
- a first bus for connecting to the computer;
- a second bus for connecting to the computer;
- a hub coupled to the first bus for connecting the computer to one or more peripheral devices;
- a controller for connecting the computer to a high-bandwidth device, the controller being switchably coupled to the hub and the second bus;
- and
- a switch for switching the controller, from being coupled to the hub, to being coupled to the second bus, when a connection to the computer is detected on the second bus.
A method of connecting one or more peripheral devices to a computer, the method comprising:
- providing a first bus for connecting to the computer;
- providing a second bus for connecting to the computer;
- coupling a hub to the first bus for connecting the computer to one or more peripheral devices;
- switchably coupling a controller for connecting the computer to a high-bandwidth device, the controlling being switchably coupled to the hub and the second bus;
- detecting a connection to the computer on the second bus;
- and
- switching the controller, from being coupled to the hub, to being coupled to the second bus, when the connection to the computer is detected on the second bus.
A method of connecting one or more peripheral devices to a computer, the method comprising:
- providing a first bus for connecting to the computer;
- providing a second bus for connecting to the computer;
- coupling a hub to the first bus for connecting the computer to one or more peripheral devices;
- switchably coupling a controller for connecting the computer to a high-bandwidth device, the controlling being switchably coupled to the hub and the second bus;
- detecting a connection to the computer on the second bus;
- and
- switching the controller, from being coupled to the hub, to being coupled to the second bus, when the connection to the computer is detected on the second bus, so as to isolate the connection to the computer on the second bus from the connection to the computer on the first bus.
