symbolic links for USB devices not working in dockers?

Recommended Posts

I have USB keys for deconz and zwave, and I am sick of having to reassign the dockers path to the USB every reboot when they are randomly assigned ttyACM0, 1,2,3 etc.

I set up the 99-usb-serial.rules to try to makes symbolic links per the tutorials:



SUBSYSTEM=="tty", ATTRS{idVendor}=="1cf1", ATTRS{idProduct}=="0030", ATTRS{serial}=="DE2149591", SYMLINK+="deconz"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0658", ATTRS{idProduct}=="0200", ATTRS{serial}=="0000:00:2d.7", SYMLINK+="zwave"


it appears that it's working, I see a link /dev/deconz pointing to /dev/ttyACM3:


ls -la /dev/deconz

lrwxrwxrwx 1 root root 7 Dec 24 11:59 /dev/deconz -> ttyACM3


However, the dockers (both deconz and home assistant) don't work when I submit the docker the /dev/deconz path, only when I send it /dev/ttyACM3.

Any ideas what I'm doing wrong? I had expected the dockers to work the same with the symbolic link path as the true path. The permissions, ownership of the link looks the same to me.
