[pvrusb2] pvrusb2 vs. em8300

[Michael Roitzsch]

Hi Mike,

I reported this problem already, but this was a long time ago, so let  
me refresh the caches: I have a pvrusb2 which somehow collides with  
an MPEG decoder card I have. The card is a DXR3 (aka Hollywood+) with  
the em8300 kernel module. The card is I2C based just like the  
pvrusb2. What happens is that the pvrusb2 does not emit any audio  
when the em8300 driver is loaded. If I prevent the em8300 module from  
loading and power-cycle the pvrusb2, everything works fine (latest  
driver snapshot). But when both devices get their drivers, the  
pvrusb2 is silent.

I have not investigated the issue until today, since I had a  
different problem with my Ubuntu not liking the em8300 driver for  
other reasons. I wanted to fix that first to make sure the pvrusb2  
problem is not related to that. Today I got things sorted out and  
headed back to the pvrusb2. Of course it still does not cooperate  
with that other driver. I grabbed two logs: one with the em8300  
driver in place (that's the broken one) and one without the em8300  
driver (that's the working one). From what I can see, the firmware1  
is not loaded in the broken case. Do you have any idea what might be  
going on here and what further data I could provide?
