transfering ibooks via usb using itouch.

Hello. I really like my ipodtouch device since I had this awesome thing since July. I was wondering how do I transfer my ibooks via usb using itunes with my itouch connected up to my pc. I am using window eyes and when I am in the side bar using the tree view under devices I see my ipod and select the cync books radio button when I want to cync my books I do check the radio buttons to make sure my ibooks are selected. Then itunes says zero books. When I go back in to the side bar view and go to the books tab and do tab around and select the list radio button I do see my ibooks are there. I also did check the itunes media folder and there is a books folder where again my books are there. So how do I get them on to my ipod touch via usb itunes way? I prefer not to use the icloud service since I want to be in control of my stuff. I also don't use wi-fi since am on the net via pc and for me it is easier that way. Any help would be really appreciated. Thank you.
