First, I wanted to apologize for not replying for a full month, as well as thank you very much for your reply. I was pulled away from this project for a couple weeks, and when I got back I was still spinning my wheels getting the driver installed. Not a problem at all. It was 67 characters and, apparently the maximum is 63. Seems like an arbitrarily short max in this day and age, and you'd think both XCode and the Developer Portal would catch that, but that's what it was. Sigh... I'm sorry I didn't think of that, as I'm aware of that limitation and actually posted about it here. FYI, you should also be aware of the version number limitation described here, which is another arbitrary restriction the kernel enforces. So, on to my current problem. The driver installs... but doesn't load. Probably because it's not matching. So I'm going to give more detailed information in the hope you can help me with this. If you haven't seen it already, I have a post here that does an extended run down of the matching
