Hi Linda. It depends on what you mean by not recognised. Does Windows detect the presence of the BookPort by making the hardware connected sound? Is it only the BookPort software that is not recognising the unit? Can he access it as a drive letter in my computer? In order to be able to help, I need to also know what operating system he is using. The problem could be one of many depending on where the route cause is. One solution isn't necessarily going to solve the problem. I await further details.

All of a sudden, when he later connected the book port to the computer to put more books on it, it didn't recognize the book port. Is the only option to uninstall the book port then reinstall it, or is there something else that can be done?
