I'm a bit confused, what this anybus stuff actually does. Is it some proprietary backplane bus, where things like eg. fieldbus adapters are attached to ? I see some struct bus_type field declaration - is that going to be some subsystem, similar to those for other bus'es (eg. pci, usb, ...) ? Maybe that deserves a bit more documentation :p --mtx -- Enrico Weigelt, metux IT consult Free software and Linux embedded engineering info@metux.net -- +49-151-27565287
