Hi there,
I also had experience with the same issue. It could be possible problem of granting access to /dev/ttyUSB0. You should try this way

# ls -la /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Apr 12 07:36 /dev/ttyUSB0

# chmod 777 /dev/ttyUSB0

# ls -la /dev/ttyUSB0
crwxrwxrwx 1 root dialout 188, 0 Apr 12 07:36 /dev/ttyUSB0


Hope this help!

Thanks @pipiche for following up.
I just bought a linux NAS and am going to move the coordinator to that rather than OpenWRT.

I am waiting for it to show up in a couple weeks.
