Usb passtrough mode, how to avoid host to get ttyACM0

1

Hello,

While using usb passtru mode, with a config like:

lxc config device add fxdev tm4c123 usb vendorid=1cbe productid=00fd mode=0666

how can I avoid host system to get /dev/ttyACM0? right now, in the programming mode it works with usb passtrough mode, but however /dev/ttyACM0 gets created in the host computer, and I have to proxy it as unix-char device.

Is there anyway, upon plugging the usb device, host does not process this device, but only the container does?

Best regards,
C.

The host processes the new device according to the udev rules found in /etc/udev/. You would need to figure out a way to set LXD to handle the device. I do not have a working example. You can start here, https://wiki.debian.org/udev
