Hi There, I have a confusing Problem: comedi works fine but I can't actually control any Ports of my DAQ card because nothing happens at the ports. I have a PIO2 card from BMC-Systems with two 8255 , and a debian woody system with comedi-0.7.65 comedilib-0.7.19 installed. I tried around and found out: -If I try to write to a port, no error is reported and comedi_errno( ) stays 0. -when I use comedi_dio_config(...) the return value is 1 instead of being 0 or -1 as described in the doc. -Subdevice flags are B0000 referencing to comedi.h that means it has no externally visible lines, but it has 24 channels. -In the past time using comedi i had to be root. But now I can call my progams from a user account without getting an error message ( I chanced no permissions ). -the card is ok ( tested with vendor software ). -I got the same "zero" behaviour by using different io-bases. The base adress given to comedi for the 8255, is it the base adress of port A? The things above may probably have no connection with my problem, but I have no Idea what causes my Problem, so I wrote them all down here. Thanks for help micha
