AHA! And to add, it now looks like the official raspberry pi repo has a 6.1 kernel that works properly with this library, BUT the Revolution Pi repository has a version that is updated to 6.6 and that does not work with this library... so this may not in fact be a raspbian issue but an issue specifically with RevPi's version of Raspian (at least for us... I cannot speak for the original poster).
