Not sure why it start to happend. Even after I have upgrade Home assistant and Tellstick it still work a little and after a while it stop working.
When I look in the log I can see it say
Error in communication with TellStick when executing action. Resetting USB
Disconnected TellStick (1781/C31) with serial A6028FPM
Rescanning USB ports
No contoller (TellStick) found, even after reset. Giving up.
Only option I have then is reboot the machine and it work a little before it stop again.
The only change I have done is I have add conbee (Zigbee support) to Home assistant.
All the others works fine, Zigbee,Z-wave and wifi
