1. connect usb keyboard.
2. physical keyboard turn off.
3. run soft keyboard and It works only one time.
4. set physical keyboard.
5. physical keyboard turn off.
6. does not work soft keyboard never when usb keyboard is connected.
해결책은 언어를 바꾸고 바로 Default를 선택하면 나오는 화면에서 바꿀 수 있네요.
I found a solution.Change Language and just select Default item of "KEYBOARD & INPUT METHODS" menu. and you can change state of Hardware(Physical keyboard) on/off.
1. click "Language & input"
2. click "Default"
3. Change state of Hardware(Physical keyboard) on/off.
