poll example program from Bob Apodaca on 2004-07-13 (gmane.linux.comedi)

I've been writing a driver and working on interrupt driven operation 
using the "poll.c" example program.  Everything is working well until I 
change the number of channels from 1 to 16 (I have a 16 channel card) 
and then:

./poll
test ret=-1
errno=22
comedi_command_test: Invalid argument

What's is also interesting is that my cmdtest driver function is never 
called (I have instrumented all my driver functions).  Any ideas?

Bob
