uc480 start_live_video() fails after close() and open()

[Feargus]

from instrumental.drivers.cameras import uc480
instruments = uc480.list_instruments()
#cam = uc480.UC480_Camera(instruments[0],reopen_policy='reuse')
#cam = uc480.UC480_Camera(instruments[0], reopen_policy='new')
cam = uc480.UC480_Camera(instruments[0])
#cam.is_open#True

cam.start_live_video()

cam.stop_live_video()

cam.close()
#cam.is_open#False

cam.open()
#cam.is_open#True

cam.start_live_video()

In the above code, the first cam.start_live_video() works fine, the second one throws an error

Changing the reopen_policy doesn't seem to matter. Am I doing something wrong here? I would really like to be able to close(), in order to be able run the normal ThorCam software from time to time.
