microtek scanner wont work

I installed an I-jam mp3 player with a removable f-drive port, it connects to the same port as my printer and scanner, the printer will still work, but now my scanner will not work,,i get an error message saying please install scanner. I am thinkingit is because of the cable that came with the removable drive…because the cable runs through the scanner to the printer, hope someone can help me with this,,,
