I suspect english is not your mother language and that you used an automated translator. The problem is it's very difficult to understand your question.
I gather you want to connect your device under android 2.3 with calibre. That can be done by using the "connect to folder" feature on calibre.
Plug your device on your computer as a disk, click on connect to folder. Go to the folder where your books will be stored on your device and here you are, you are have connected your device to calibre.
