We used to check the page list first. However, we found several devices
that we did not discover correctly because the pages, while present,
were not advertised in page 0 and thus ignored. So not checking the
supported pages first is a feature.

What exactly is the problem you are experiencing wrt. your target
getting an inquiry for the CPR page?
