ZWave controller should be reset at start of program?

[dhylands]

If the app crashes while the zwave dongle is inclusion mode, and you then restart the app, the dongle seems to still be in a state where many devices will timout. I observed that my Leviton devices all got timeouts.

Unplugging and replugging the dongle seemed to resolve this.

We might need to do a controller (dongle) reset. Ideally we'd detect the state that the controller is in and get it out of that state, and only reset the controller if absolutely required.

@dhylands Is this still an issue?

I think so. If the Pi happened to get reset while the gateway was in the middle of sending data, I think that's its possible for the dongle to get into a confused state. I've definitely seen cases where unplugging and plugging in the zigbee dongle made things work again.

On some of the RPis it is apparently possible to power cycle some of the USB ports.
