Celestron Skyris

Dear all,
Is there a way to use the Celestron Skyris cam's? I have both the 618m and the 274c and tried them as DMK or V4L2 but get the message:

2019-11-23T14:08:37: [ERROR] Error: unable to open device. Cannot identify /dev/video0: 2, No such file or directory

Is this because of USB3? I would like to use them off course!

Cheers, Arnold
