ml4700 usb 버전에도 허브가 있나요?

저도 전체가 그런지는 모르겠는데요 요즘 나오는 제품에는 없는거 같네요올해 4월에 구매한 4700 usb에는 허브가 없습니다~

cherry 영문홈페이지에서 확인한 결과 PS/2 인터페이스 방식에는 PS/2 허브가 존재하지만, USB 인터페이스 방식은 PS/2 허브나 USB 허브가 존재하지 않다고 나와있네요.  아래는 CHERRY 영문홈페이지( http://www.cherrycorp.com/ )와 독일어 홈페이지 영문버전(http://www.cherry.de) 에 나와 있는 4700 모델에 관한 설명 자료이니 참고하셔요.Main Part NumbersG84-4700LPBUS-0 Light grey, PS/2 Interface, 21 programmable keys, 4 relegendable, ML keyswitches, second PS/2 port for keyboard  G84-4700LPBUS-2 Black, PS/2 Interface, 21 programmable keys, 4 relegendable, ML keyswitches, second PS/2 port for keyboard  G84-4700 LUCUS-0 Light grey, USB Interface, 21 programmable keys, 4 relegendable, ML keyswitches  G84-4700 LUCUS-2 Black, USB Interface, 21 programmable keys, 4 relegendable, ML keyswitches출처: http://www.cherrycorp.com/english/keyboards/Office/Slim_Line_Prg_Kypd/index.htmInterface: PS/2System requirements: PS/2 connectionConnection sockets:PS/2 port (for connecting the keypad between the computer and standard keyboard)Number of programmable keys: 20 (physically in the internal memory)Product approvals: UL  CE  FCC  VDE Delivery Volume:Operating instructions in hard copy(possible country/layout versions, others available on request)Interface: USB (can be connected to PS/2 via adapter.
