You should not look at there. This proc file lists everything but RTDM devi=
ces.

That is common comedi behaviour. So far, the comedi drivers are listed,
they are available in the kernel. However, you have to attach them so as
to make them reachable (thanks to comedi_config).

Once the attach will be done, you will see your driver appear in
/proc/comedi/devices.

If the comedi_config did not work, the problem is here. In such case,
could you send the traces?
