It would be useful , if I could reproduce the problem using a standard component of the PC to trig an IT like the PLX soft register, in order produce a regression test and some people being able to reproduce it.Supposing the same problem should appear :-) Best Regards Steph > Regards. > _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
