Hi Folks, I’ve been wrestling this one for a while now-
I’ve HA 2021.7.0.dev w/ ESXI 7 and Ubuntu 20.04 on a HP Microserver (forget which one, not new), using the deprecated Z-wave integration.
My Aoetec z-wave stick has been fine for a year or two but has just stopped working after a reboot of the ESXI platform.
OZW log shows-
Info, Opening controller /dev/ttyACM0
Info, Trying to open serial port /dev/ttyACM0 (attempt 1)
Error, ERROR: Cannot open serial port /dev/ttyACM0. Error code 5
Error, ERROR: Failed to open serial port /dev/ttyACM0
If I build a new VM and install same setup, add the integration, start z-wave - all is fine, hence I’m confident with the USB setup of ESXI, the stick, the key etc.
Something in this VM (which has identical settings to the new one mentioned above) seems to be locking the USB/serial comms but I cant fathom it.
Appreciate any help.
