Hi,<div><br></div><div>I tried your suggestion but unfortunately it does not work.

<div>Hello,</div>
<div> </div>
<div>I solved similar issue by adding "chmod 666 /dev/ttyUSB0" at host boot.</div>
<div>And I have this in lxc container:</div>
<div>
<div># rfxcom<br>
lxc.cgroup.devices.allow = c 188:* rwm<br>
lxc.mount.entry = /dev/ttyUSB0 dev/ttyUSB0 none bind,optional</div>
<div> </div>
</div>
<div>Do not know if it is proper way but it works for me.</div>

<div name="quoted-content">Start by checking the host's syslog (right after reproducing the failure<br>
in the container) and look for DENIED messages. Report them here.<br>
<br>
Then do<br>
<br>
strace -f -ostrace.out whatever-command-you-run-that-fails<br>
<br>
in the container. Look at the output of<br>
<br>
egrep -e '(EPERM|EACCES)' strace.out<br>
<br>
(or send it here)<br>
