Just downloaded the docker container on CentOS 8. When I plug in my UPS, it gets assigned to "/dev/bus/usb/00x/00x". When I use the docker run command I use:

docker run --name tripplite --detach --publish 3943:3943 --device /dev/bus/usb/00x/00x -e UPS_NAME="Tripplite" -e UPS_DRIVER=usbhid-ups -e UPS_DESC=Tripplite -e API_USER="upsmon" -e API_PASSWORD="xxxxx" upshift/nut-upsd

If the device path was originally "/dev/bus/usb/002/001" it will get reassigned to "/dev/bus/usb/002/002" after starting the docker container, which results in never ending "Poll UPS [Tripplite@localhost] failed - Data stale" messages in the log. I'm assuming because the UPS has moved to a new device path as a result of the run command forcing it to move.

Not sure what to do to fix this.
