Recently I have started working on a special input system for a local public project. I have chosen to use a teensy 2.0 and a tmk's keyboard firmware as the basis of my project but I have run into issues with N key rollover.
Specifically only 6 of the 7 total keys will every register at one time. I have tested extensively and each key works individually, but when I try to trigger all 7 keys at once it does not register one key. Normally the key that does not trigger is the D key but not always. when I test the tester by pressing more than 7 keys on my 910 they all register correctly so the testing software is not the issue.
Here is the links to the keyboard hex file calculator and related stuff.

I may be mistaken, but I think that TMK over USB uses the standard USB HID descriptors which can only send six keys at a time. Your links don't show anything more than the tools that you are using, so I'm not sure what you are actually trying to do, and this is just a guess as to what your issue might be.
