Spinnaker: Camera is not communicating in U3V protocol #4

Open evieeangeline opened 9 months ago

evieeangeline commented 9 months ago

Hi, I'm attempting to communicate with a Chameleon CMLN-13S2M.

I assume the error below is because it uses USB 2.0. Does this library support USB2 or only USB3? 

>>> from rotpy.system import SpinSystem 
>>> from rotpy.camera import CameraList 
>>> system = SpinSystem()
>>> cameras = CameraList.create_from_system(system, True, True) 
>>> cameras.get_size()
1
>>> camera = cameras.create_camera_by_serial('21408479')
>>> camera.init_cam()
