Here's the latest patch I've got. List of changes:
* 5-byte diseqc for supporting cards (USALS support)
* Fixes garbage commands caused by tone/power and tuner command buffer
conflict.
* Mini-DiSEqC commands corrected based on observations with a scope.
* More reliable about changing desired LNB voltage (though it still
won't switch it until tuning)
* Error reporting is much more thorough -- any failed commands should
now return a failure code for the ioctl. If you see applications
erroring out with failed ioctls, this is why. But it's much better this
way -- the command would have failed either way, but now the application
is told about it, and can retry, etc. -- or even better, we can actually
fix any problems that are revealed.
* Doesn't update internal state on unsuccessful commands to avoid cached
state diverging from real state.
* Avoids resending redundant tone/power commands.
It applied cleanly but it didn't work, maybe it never turned the power on?
I took a guess and made these changes, now it is working again...
