Beats me. Why do you assume that Comedi/RTDM provides more support
compared to Analogy, since it is stated that Analogy started off from
the Comedi/RTDM code base, months ago?
The reasons why you can't put original Comedi drivers on top of Analogy
did exist with Comedi/RTDM: the internal layers and APIs have been
refactored.
If you do want to help, you may want investing your time in developing
and testing a better code base like Analogy with other people, instead
of re-opening a dead development effort all alone.
