[cpia] Re:IntelPlay QX3 lights.

[Sam Hart]

One thing you have to be aware of with respect to the IntelPlay QX3 and
it's lights... the cpia module in the current and semi-recent kernels has
the /proc/cpia interface turned off (I think they said it was for security
reasons). I actually checked on this very same thing a month or two ago.

You have two options to get it to work:

1) Find an older kernel which still has it turned on (which is what I did,
but I have already deployed that machine, so I forget the exact kernel
version :-/ )

2) Replace the cpia code in a new or current kernel source with the cpia
code from their SourceForge CVS, and recompile the kernel (I was told this
should work, but I did not test it myself ;-)

Once you have a cpia module that's either *fixed* or at least with an
enabled /proc/cpia interface, then the "echo ... > /proc/cpia/video" will
work again.

(also, you need a patch to make cpia-control work again with new versions
of its dependant software. I don't have the patch on me right now, but I
think it was posted to this list about a month ago, so you should be able
to find it with a bit of effort... or someone else might have it handy ;-)
