[ros-users] is a native ROS device possible?

[John Galloway]

It appears (i.e. just reading the docs, I haven't brought up a ROS env yet) that at present every ROS device has to have an executable (or driver) on a host (which is found in the package for that device).  It would seem ideal that a device using USB (for example) could have its driver embedded to allow a generic USB driver to detect that this is a ROS device and link it into the graph of nodes (allowing the device to publish and subscribe etc) without a device specific driver being needed.  Is this possible within the current APIs?
