I have a usb attached to my ubuntu machine (16.04) and trying to access
that device from unprivileged lxc container.
By access I mean, enumerate and do I/O on that device.
I have written a small program using libusb library and using that libusb
executable to enumerate,read/write usb device from container
Please find attached lxc config file and libusb executable.
I have found plenty of examples in various forums but nothing worked for me.
Tried the following:
1. Added below entries in lxc config file
lxc.cgroup.devices.allow = b 8:* rwm
lxc.mount.entry = /dev/bus/usb/001/ dev/bus/usb/001/ none bind,create=dir 0
lxc.mount.entry = /dev/sdc /home/oxpd/.local/share/lxc/Test/rootfs/dev/sdc
none bind,create=file 0 0
lxc.mount.entry = /dev/sdc1
/home/oxpd/.local/share/lxc/Test/rootfs/dev/sdc1 none bind,create=file 0 0
2. Changed device owner to 100000
3. changed device permission to 777.on the host
when I run the libusb executable on host, all the attached device are
listed, but the same when I run inside the container it says 0 devices are
Is there any other configuration I am missing. Please help.
Thanks & Regards,
