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 would advise to not do this: since disabling current limiting etc
will cause a large problem in the case of a short circuit thereby no
protection to the hardware. In such an event, it could probably damage
the tracks carrying power on the card as well as the tracks on the
motherboard, and in some cases the gold finches themselves and or the
PCI connector.
Generally, there are only a few devices capable of sourcing> 0.5A, So
I wonder ....

for the few devices I do have, you seem to be for sure right.
All the Creatix stuff drawing up to 900mA on a potentially dual isl6405
has direct voltage from the PSU over an extra floppy connector.
Max. 500mA should be sufficient with a DiSEqC 1.2 compliant rotor.
Nothing else should come above that limit.
I wonder, if someone close in reading specs just now, can tell if 900mA
can be sufficient for two rotors ;)
Andre, BTW, assuming you still have a CTX944 (md8800 Quad), can you
measure if the 16be:0008 device really does switch between 13 and 18V.
You seem to mistake me for someone else. I do not have a CTX944 and
never had.
Regards
André
