摘要: A connection switching device for a telephone device supporting a PSTN function and a VoIP function and taking the PSTN function as a default voice communication function is disclosed. The connection switching device includes a dual tone multi-frequency (DTMF) receiver for determining whether a phone number inputted to the telephone device includes a specified trigger code, and a control unit coupled to the DTMF receiver for switching the default voice communication function from the PSTN function to the VoIP function when a decision result of the DTMF receiver indicates that the phone number includes the specified trigger code.

摘要: A USB HUB is provided. The USB HUB comprises a wireless communication module, a storage module, a USB interface connected to a host outside of the USB HUB and a HUB controller. The storage module stores a driver program of the wireless communication module. The USB interface transfers data with the host. The HUB controller is coupled to the USB interface, the wireless communication module and the storage module. The HUB controller disables the storage module and enables the wireless communication module when the driver program has been installed in the host.
