Greetings:

I am trying out a new TBS 8920 using the 2.6.30 built-in driver and it
fails to initialize. Here are the dmesg lines:

qpc$ dmesg | grep cx88\\[1\\]

I have not yet built my own driver from current linuxtv.org source but
I expect I will need to do so. Is there anything anyone can discern
from what I have included here?
