How to find USB devices in local add on

Hi all,

I followed the hello world tuto for building a local add on just fine, but I’ve since moved on to trying to installing the daemon apcupsd which will monitor uninterrupted power supplies from APC.

Unfortunately it keeps reporting that it cannot find the UPS device.
When I “ls /dev” on my container I see very few items. When I do the same on the home assistant container I see a lot more.

I have this in my config.json
“ports”: {
“3551/tcp”: 3551,
“3551/udp”: 3351
“devices”: ["/dev/bus/usb:/dev/bus/usb:rwm"],

but it doesn’t seem to have had any effect.

I read on the ResinOs site that all the devices (/dev) are available to containers by default, but I’m not getting seeing that here.

Has anyone got any ideas? It is a plugin that could be useful to others if I could just get the darn thing working!

did you ever found out?
