    摘要: A KVM device supporting transmission of SuperSpeed USB signal and DisplayPort video signal is disclosed. The KVM device comprises a first USB Type-C connector, a first USB Type-C switch, a second USB Type-C connector, a second USB Type-C switch, a USB switch, a video switch, a control unit, a video connector, and at least one USB connector. When using this KVM device, the first USB Type-C connector and the second USB Type-C connector are electrically connected to a host electronic device through a first USB Type-C cable and a second USB Type-C cable, respectively. Therefore, the KVM device transmits DisplayPort video signal between the host computer and an external display device that is coupled to the video connector. Moreover, the KVM device also transmits SuperSpeed USB signal between the host computer and an external electronic device that is coupled to the USB connector.

    摘要: The present invention mainly discloses a storage device capable of controlling peripheral devices, which comprises a micro processing unit, a communication unit and a storage unit. Particularly, the storage unit is separated into a plurality of storage blocks and one file table block based on a file system, and parts of the storage blocks storing with device accessing files are further set to be a peripheral device controlling block. After connecting the storage device to a peripheral device and a host electronic device, the host electronic device can control the peripheral device through changing contents of the device accessing files. Thus, for the peripheral device manufactures, it just needs to develop driver software of this storage device and an application program for accessing the device accessing file, but does not need to develop corresponding peripheral device driver softwares compatible with various host operating systems, such as Windows and iOS.
