    • At startup, divided data blocks are received from other authentication devices and are assembled together with the local divided data block to reconstitute first authentication data. After a prescribed time interval, divided data blocks are again received from other authentication devices and are assembled together with the local divided data block to reconstitute second authentication data. The first authentication data and the second authentication data are cross-checked, and the legitimacy of the other authentication devices is decided; in the event that the other authentication devices are legitimate devices, one authentication device among the multiplicity of authentication devices re-divides the second authentication data into a multiplicity of divided data blocks for re-distribution, and a process of reconstituting the authentication data from the divided data, cross-checking the reconstituted data with the first authentication data, and deciding whether the other authentication devices are legitimate devices is repeated at prescribed intervals.

    • It is an object to provide a USB upstream device, a USB connector, and a USB cable, capable of operating stably by preventing malfunction due to a signal line defined as a high impedance state depending on a data transmission mode in the USB upstream device, when inserting or removing the USB upstream device into or from the USB. In a USP upstream device 1, a switch circuit 11 is provided between a signal line D− and grounding voltage. When the USB upstream device 1 is connected to the USB, power is supplied through VBUS line in the USB cable and the signal line D− is cut off from the grounding voltage. When cut off from the USB, the power supply through the VBUS line is cut off, and the switch circuit 11 conducts. Then, a discharge route is established. Unnecessary charge such as leak current or the like is discharged to the grounding voltage through the switch circuit 11. As a result, in a state separated from the USB, a voltage level of the signal line D− is maintained at a low voltage level.
    • 本发明的目的是提供一种USB上游装置,USB连接器和USB电缆,其能够通过根据USB上游装置中的数据传输模式防止由于被定义为高阻抗状态的信号线的故障而稳定地操作, 将USB上游设备插入或取出USB。 在USP上游装置1中,在信号线D和接地电压之间设置开关电路11。 当USB上游设备1连接到USB时,通过USB电缆中的VBUS线供电,信号线D-从接地电压切断。 当从USB断开时,通过VBUS线的电源被切断,并且开关电路11进行导通。 然后,建立排放路线。 诸如泄漏电流等的不必要的电荷通过开关电路11被放电到接地电压。 结果,在与USB分离的状态下,信号线D的电压电平保持在低电压电平。
