Hi Alexis,
Thanks a lot !!
I switched to the analogy branch, configured the kernel to build the analogy
kernel moduels and compiled it. However, here is what I get:
r...@xenomai:~# dmesg
...snip...

I don't really know how to use analogy_config... since

comedi_config: comedi_snd_attach failed ret=-22
when I run
r...@xenomai:/usr/xenomai/bin# ./cmd_read
cmd_read: a4l_fill_desc failed (ret=-22)

...
which is I guess due to the unsuccessful analogy_config. My question is,
which driver do I have to use ?
Thanks,
peter
