Sharing Fat32 drive wirelessly between OSX and XP

I have a usb external hdd shared wirelessly over my network through the usb connection on my time capsule. The drive works fine through OSX but is not recognized by XP i have installed via BC. I assume this is simply a matter of configuring it on XP but I have no idea where to start.

No configuration should be needed on XP, it should sense the drive if it's formatted correctly.

Again it recognizes the drive no problems if it is directly connected to the usb port. My problem is getting it to recognize the drive when it is plugged into my Time Capsule's usb and shared over my wireless network.

Would this question be better suited in a different forum (Wireless Forum)?
