Hi I am a new user of the C-BUS although I did a C-bus training course last December. My boss is going to build a house with C-bus, and he wants me to do some testing of C-bus components. I do have a C-bus Demo with 5500PCU, a relay and dimmer and couple of input units, but I ccouldn't connect pc, for toolkit it says 'PCI found failed identify'.:( Did anyone meet that before?
