As described above, the process of installing the host program in the host computer HC is the process of installing the host program (S30) of FIG.

Even after the host program installation process (S30) is finished, the extended monitors (D, D1 to D3) and the expansion hubs (S, S1 to S3) are separated from each other, so automatic mapping is not possible. Therefore, when the installation of the host program (HP) is completed, the host program (HP) moves the connected extension hubs (S, S1 to S3) and the extended monitors (D, D1 to D3) to the USB key lock type authentication device (A). After recognizing the connection status, the user can register the user account and password, and assign the IP to configure the extended computer (EC) environment.

Register as a subordinate device of the expansion computer corresponding to S1 to S3). This process becomes an input / output device dynamic allocation process not shown in FIG. The mapping of the expansion hubs (S, S1 to S3) and the expansion monitors (D, D1 to D3), the virtual driver generation and the mapping process for the peripheral devices become the expansion hub and the expansion monitor mapping process (S43) of FIG. .

When one expansion hub and the expansion monitor mapping process (S43) are completed, the host program (HP) is the entire expansion monitors (D, D1 to D3) or expansion hubs (S, S1 to S3) recognized by the host computer (HC). The process returns to the identification screen sequential output process S41 until the extended hub and the extended monitor mapping process S43 are performed, and the process is repeatedly performed. When the process is completed, the process returns to the process of FIG. S44).

The extended computer setting process S40 of FIG. 10 may be performed following the host program installation process S40 or may be performed after reboot of the host computer HC if necessary.
