Hi,
The newer revision cards should be able to shut down LNB power when the
card is closed. This is what the Windows driver does; not yet
implemented in Linux.
I'd like to document the different variants of this card on the wiki.
Can you send me the output of lspci -vvnn for your variant? If you have
Windows, can you also send me some RegSpy states similar to the ones I'm
attaching to this mail?
Regards
JD
