Vostro 200 Slim Tower Flexbay

Hi,

I was wondering if anyone knew what the pin-outs on the vostro 200 slim tower flexbay connector were.

I am looking to put a floppy drive and media card reader in the 3.5" bay on my vostro 200 slim tower;  but noticed that both usb headers are already being used.  the flexbay header is available but based on what i'm reading online, different dell models have different pin outs for the flexbay which may or may not be comaptible with the usb headers provided with media card readers.

any help with this would be much appreciated.
