[ivtv-users] Why is HVR 1600 recognized on one system and not the other.

[test]

I have 2 Ubuntu systems which are not identicle.
I installed the Hauppauge HVR 1600 in system A (my testing system). I 
followed the info from the Ubuntu forum. The card was detected. So I 
performed the same steps on system B ( my working system). Again, the 
card was detected.

Here is the result from dmesg | grep cx18...

Now, I have the card detected on system B where I want to use it. So for 
further testing I reinstalled Ubuntu on system A and reinstalled the 
card. dmesg | grep cx18 now gives a differant result. Here is the result...

What does this new dmesg result indicate and what should I do to correct it?
I want to perfect it on the testing system before I do any more 
configuring on the working system, and therefore I must understand the 
problem.
