I'm having some issues with the Zwave interface, I don't actually think its Indigo but potentially a Mac issue.
About 5 times maybe more per day the Zwave stick stops working, the event log shows this as "lost connection with interface" and then "send get version failed after 9 attempts" followed by "restarting serial connection in 5.0 seconds"
Eventually it will start working again, but the only way to speed the process up is to unplug the stick and reinsert it. This always works, restarting the computer does not cure it as only a full power down and restart does that.
It's as if the stick is faulty but I replaced it and have exactly the same issue with the new one, I have a RFX device in another USB port and it works ok. I do have a short extension cable to the USB, but have tried plugging in directly and still have the same issues.
Looking for ideas as at the moment I have not got a clue!
