I advise not to pull this change into the kernel sources.
The card has only been testet with the a maximum current of 515mA.
Anything above is outside the specification for this card.


I'm currently running two of these cards in the same box with this
patch.
Actually, later on I've even set curlim = SEC_CURRENT_LIM_OFF because
sometimes diseqc wasn't working fine and that seemed to solve the
problem.

I used to have skystar2 cards before and I did not run into those
issues. Diseqc just worked fine.

For reference each tt s2 is plugged to a diseqc switch with 4 output,
each output connected to a quad lnb.


How come there is such a high current drain to drive the switch plus the LNBs? From what I understand, the switch should only power one LNB at a time. Usually the switch plus the LNB should not drain more than 300-400mA, or am I wrong here?

Is there another way to solve this ?
Maybe add a module parameter for people who want to override the
default ?


I think this could be done. Nevertheless, the card would still operate outside its specification.

 André
