Hi, A couple of days ago I updated my system from Xenomai 2.2.0 and kernel 2.6.17.8 to Xenomai 2.3.0 and kernel 2.6.19.2. Everything worked well until I tried to open my driver for the parallel port. The function rt_dev_open() always returns -EBUSY even after loading the module and trying to open the device for the first time. I had been using the driver for several weeks without any problems and havn't touched the code. Any hints?
Regards Nathan
