The camera1394 driver seems to leave the Point Grey Grasshopper2 (IEEE 1394b version) ON after it is stopped (roscore included).
I say it seems because the camera case is hot after I stop the driver. Yes, that's how I know it remains ON. If you know, by the way, of any other way to check to power state of the camera (or the firewire bus), please, let me know.
With coriander the camera case goes to ambient temperature after I exit coriander (actually I press the power OFF button before exit), so it seems it's switching the camera off correctly.
Does anybody else experienced a similar problem/behaviour?
How can I fix it? Should I touch the camera1394 (pkg) driver?
