How to enable keyboard and mouse as input in qtopia-2.1.1

Hi ,
I am using qtopia-2.1.1 and qt-embedded- 2.3.10 in my target (ARM11)
I am using LCD for display purpose.Key board and mouse for input purpose in my embedded Product.
Now how can I disable Touchscreen feature and enable mouse and keyboard as input methods in qtopia-2.1.1 .Key board features means i wanted to use 5 to 6 buttons of key board for initial selection of application and moving back and front in the application.
Kindly guide me in this regard.

Thanks in advance,

Regards,
