I think you would need to adjust the devices permissions for your 
container, for the usb nodes.. but I'm not sure.. then the container 
could talk to the USB devices over USB, and handle the hotswapping.
However I'd expect conflicts to occur with the host trying to talk to 
the same device.
Try adding this to your config file?

lxc.cgroup.devices.allow = c 189:* rwm

I'm no expert and I haven't tried this myself, mind, so you might prefer 
to wait for someone more qualified to answer.
