iTunes doesn't recognize my 4th Gen iPod Touch

When I plug in my iPod Touch iTunes informs me there was an error and it cannot read my iPod, and that the only solution is to restore my iPod to factory settings. I have tried this, multiple times, in hopes it would fix my problem, yet everytime it only registers my iPod until the next time I try to connect my iPod, and then it once again tells me I need to restore it to factory settings. Has anyone had this problem and do you know a more permanent solution rather than restoring it everytime I wish to update my library?
