Hi,

On my FC6 system, I made an adjustment so that
/usr/include/linux/ contains the *.h files otherwise
declared missing when compiling, and got Qastrocam to
compile and run.  However it is definitely NOT
supporting the TUC LED mode (this on FC6 Linux) with
the stock FC6 PWC driver!!!   It definitely worked on
RHEL4 when I got PWC to compile.  Difference is I
compiled Saillard.org pwc driver latest snapshot
myself on RHEL4. But on FC6 I still cannot get pwc to
compile.  I believe the pwc which comes stock with FC6
is NOT supporting the TUC LED LX mode - ie. it is NOT
fully supporting the SPC900NC whereas before it was
when I got pwc to compile.

Any ideas on this???

Peter
