Abstract:
1. A method of controlling a host device which is connected to at least one image scanning device and is connected to another host device connected to at least one image scanning device, the method comprising: when the host device executes an application, executing, by the host device, a driver that corresponds to the executed application from among the plurality of drivers which are supported by an integrated driver; selecting, by the host device, an image scanning device from among at least one image scanning device connected to the host device and at least one image scanning device connected to the other host device; generating, by the host device, a signal for controlling the selected image scanning device according to a first protocol corresponding to the executed driver; converting, by the host device, the generated signal according to a second protocol which is different from the first protocol; and when the selected image scanning device is connected to the host device, transferring, by the host device, the converted signal to the selected image scanning device, and when the selected image scanning device is connected to the other host device, transferring, by the host device, the converted signal to the other host device, wherein the first protocol and the second protocol are communication protocols for data exchange between the host device and an image scanning device.
