[linux-dvb] Compro VideoMate DVB-T300 auto detect problem- suggested code fix

James, Hartmut,
I have also had "interesting" PCI ID behaviour from my Compro VideoMate, on

I have seen the correct PCI ID in dmesg, but I usually get 1850:0000 (or was
it 185b:0000?). I can't remember the exact ID. I've been using a
modprobe.conf workaround to get the saa7134-dvb module loaded.

My suspicion was that it was related to whether the machine was reset or
went through a power-down.

I have had a somewhat tortured path to getting things going also. There are
many points to stumble on. But I am getting close. I have had the remote
working. But perhaps like you, I get only brief periods to work on it,
perhaps once overy 4 days to 2 weeks.
