I can't really see much else. As Klaus says, even with the incomplete DISEQC 
sequence, it worked OK in 1.0.1, yet doesn't in >=1.1.0 (once the LNB power 
is on).

In av7110_hw.c, I see it just sends commands at the firmware to send diseqc 
commands, and doesn't hit the hardware (as you say). The code I _can_ see 
looks pretty much the same as in 1.0.1. Would it be possible to try the 1.0.1 
firmware in the 1.1.0 driver?
