[pvrusb2] HVR 1900: How do I use analogue only (avoid using it for DVB) ?

I don't have this box yet, but I am still wondering:

When I use it with vdr and its plugin pvrinput, vdr will first open the dvb 
devices (/dev/dvb/adapterX). When initialzing the plugins, pvrinput will try 
to open /dev/videoX. As far as I know this won't work because we cannot use 
DVB-T and analogue the same time.

There is no way to force vdr to ignore the pvrusb2 DVB device. It is a DVB 
application, and it will always open all found DVB devices.

Am I right that the pvrusb2.ko module handles both analogue and DVB? So there 
is no way to blacklist a dvb module.

Disabling "pvrusb2 ATSC/DVB support" in the kernel config works according to a 
user report. But this would mean that every pvrinput user needs to rebuild 
the kernel or modules. I hope there is an easier way.

Maybe it is possible to add new module options?
for example 
parm:           disable_video:1=do not use analogue video (int)
parm:           disable_dvb:1=do not use DVB (int)

Or did I miss something?


Mike, by the way: I think you can delete this option:

     parm:           vbi_nr:Offset for device's vbi dev minor (array of int)

as long as VBI is not supported.
