Good for advantech, bad for you.

If you insist on using an outdated version (0.7.60 is three years old)
because your vendor recommends this, please ask your vendor for support.

If you want support from this mailing list you will have much better luck if
you use a newer version.

Also, please make sure not to confuse your version of comedi_lib_ and comedi.

Maybe if you post some relevant parts of your code someone would be able to
spot an error.

But please try a current version of comedilib and comedi first.
