ABSTRACT:
An electronic apparatus having switching unit is described. The electronic apparatus includes a first peripheral device, a second peripheral device and a switching unit. The first peripheral device communicates with the host unit. The second peripheral device communicates with the host unit and the first peripheral device, respectively. The switching unit switches to the host unit and the first peripheral device for allowing the host unit to access the first peripheral device via a first path. The switching unit switches to the host unit and the second peripheral device for allowing the host unit to access the second peripheral device via a second path. The switching unit switches to the first peripheral device and the second peripheral device for allowing the first peripheral device to access the second peripheral device via a third path.
