Hello Jan,
Thanks for the link bu t I did go to those few hardcore X-10 user forum already.
I did also install the Marmitek AHP client properly before connecting the CM15A USB interface as said.
The AHP client is working fine & reports it can't find the USB controller
Win7 refused to recognize it, the very reason I'm now looking at debugging the connection somehow until X-10 resume (if they ever) supporting their software.
Maybe the CM15A will end up at the electronic recycling
In any event, thanks for your support & now I will start reading...
