USB camera connection

I have a usb cable which came with the camera,(refurbished - from ebay). The usb cable I have will not fit into any adapter or the docking station. There is a small (about 1 in square) adapter that plugs into the bottom of the camera which, also fits onto the docking station.
Still it has no port that the usb cable will fit into. No matter what combination I have tried I cannot connect the camera to the usb cable so I can view stuff or upload it to my pc. I do have the cable which contains the 3 rca jacks for plugging into a tv for viewing. It appears that I do not have the correct usb cable meant for this camera..... The manual I received with the camera is primarily a "users manual" & does display any parts or directions for hooking anything together..... Sure hope this makes sense...as I'm still learning how to use this thing. A digital camera dummy I suppose......Still haven't been able to use the remote that came with it either...not sure if it works.... Thank you kindly - Hope you can help....
