Almost offtopic Mike, I don't have any audio ports in that front panel hub.

What I did find was the sd_mod wasn't, because it was builtin.  Rebuilding a 
new kernel with sd_mod as a module, and while it set it up as sde (I have NDI 
where abcd went), its now mounted and readable.

Is that considered a kernal bug?  Damnifiknow.
