The number of audible books will depend upon the size of the books and = the size of the card. For example, if you have a one gig card, and your = average audible book is 100 meg, then you will be able to put nine to = ten books on the card since 100 megs goes into one gig approximately ten = times. You are looking for a USB hub; I would call PC Connection at = 1800-8000005 and see what they have.
