1. An interface device capable of supporting an unknown I/O device, comprising:
a transmission module, used for receiving a control signal sent by an I/O device and sending a feedback signal to said I/O device; a signal process module, used for generating a control indicating signal according to said control signal and generating said feedback signal according to a feedback indicating signal; and a USB interface, used for sending said control indicating signal to a data process device and receiving said feedback indicating signal from said data process device, wherein, information content of said control indicating signal and information content of said feedback indicating signal both include the information of a first device description unit and a first interaction description unit contained in a first device index chart, and wherein said data process device comprises a driver program, when said driver program is able to identify said I/O device through said first device index chart, a second device index chart is established; when said driver program is unable to identify said I/O device through said first device index chart, a third device index chart is established, wherein columns of said second device index chart comprise a second device description unit and a second interaction description unit, columns of said third device index chart comprise a third device description unit and a third interaction description unit, and said third interaction description unit comprises raw data. |
