Query: Doesn't work with iTunes music that resides on a USB drive

I'm sure the product works fine in most situations. My iTunes music resides on an external USB drive. Whenever I plug this in, it makes my USB drive literally go away, it drops out of site. Powering my drive off/on a couple times gets it back. I thought it was something else, but I've been able to re-create the problem a couple times and I am sure its caused by my iPod using this cable.
