Your analog input problems are probably due to not letting the inputs settle 
after changing channels.  Try using comedi_read_delayed().

The analog output does seem to be broken for the daqcard-1200, as I've gotten 
a few reports on it now.  I'm not sure why yet, the programming of the analog 
output is simple, and according to the manual is the same as the other board 
models (which work).  Have you tried using the unipolar output range (range 
1)?
