USB access for Android development (aka adb)

[bryanlarsen]

Here's how I got USB access working. (14.04 host and container):

sudo mkdir /dev/bus in the container

vagrant halt

add to Vagrantfile:

 config.vm.provider "lxc" do |lxc, override|
   lxc.customize 'cgroup.devices.allow', 'c 189:* rwm'
   lxc.customize 'mount.entry', '/dev/bus dev/bus none bind,optional 0 0'
 end

You should be able to just use config.vm.synced_folder('/dev/bus', '/dev/bus'). The default mount options for synced folders with LXC are bind,create=dir, which will auto-create the target directory in the container. I don't think you need the optional option, since I think that /dev/bus always exists on the host (that option just makes the container startup continue if the mount can't be created). The vagrant-lxc driver will also helpfully strip the leading / from the target folder. If you need to pass any other options, you can pass your own set of mount options as an array of strings as a third argument to synced_folder.
