I have also been having the same issues. When linking an iBook from the iTunes store link, My Materials or from my Mac I am able to link the book, but the 'Link to a Chapter' pop-up does not appear as it should to allow deep-linking.
Believe me, I have tried every possible combination of resources and approaches, all with correctly referenced contents data, but I just can't get the deep linking option to show!
I am currently in email discussion with iTunes U support to try to resolve the issue. We have tried linking identical iBooks in our iTunes U courses and the screenshots from the support team show the 'Link to Chapter' option, yet in my course the option never appears!
I am beginning to think this may be a regional problem, as the support team is in the USA while I am based in Switzerland. He has said that he will pass it on to the engineers to see if they have a solution, so I will keep you updated once I hear more...
Really want to use this feature, as it makes life much easier for my younger students.
