how to use dvb_attach (was: Re: Re: Error unloading WinTV NOVA T USB2)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Mario,

The wrong use_count for the dib3000mc is most likely because I'm not using 
the dvb_attach-function for attaching the demod/frontend, because the 
prototype of the dib3000mc_attach is not exactly the same as for other 
demod-drivers.

Why? Because with the dib3000mc_attach (and with the future coming 
dib7000m_attach and dib7000p_attach) we can attach more than one demod at 
the same time - will be used on devices arriving late fall/autumn).

Can someone please advise me how to proceed? 

thanks in advance,
Patrick.
