I'm trying to mount a USB Zwave device in a container and I had this configuration working in an older installation but now I'm running into permission issues.

Here is my conf file for the container:

Code: 
arch: amd64
cores: 2
hostname: hass
memory: 8192
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=6E:AF:59:BD:DA:D9,ip=dhcp,type=veth
ostype: debian
rootfs: local-zfs:subvol-100-disk-0,size=20G
swap: 512
unprivileged: 1
lxc.prlimit.nofile: 65535
lxc.cgroup.devices.allow: c 189:131 rwm
lxc.mount.entry: /dev/bus/usb/002/004 dev/bus/usb/002/004 none bind,optional,create=file
lxc.cgroup.devices.allow: c 166:0 rwm
lxc.mount.entry: /dev/ttyACM0 dev/ttyACM0 none bind,optional,create=file

On the container, when running an ls al I get this:

Code: 
homeassistant@hass:~$ ls -al /dev/ttyACM0
crw-rw-rw- 1 nobody nogroup 166, 0 May 26 05:15 /dev/ttyACM0

Why am I getting "nobody nogroup". I've read it has something to do with UIDs and unprivileged containers but I'm a little lost how I can fix this.
 
Did you configuration run befor4 also as unprivileged container? That default changed in the GUI quite recently, and thus the permissions /dev/ttyACM0 are probably root:root on the outside and hence not translated to root inside the container.

You could try to create the container as a privileged container, or change the device-ownership on the outside

hope this helps!
