Spyder4 no sensor->get_sample

[FireCulex]

$ colormgr get-sensor-reading lcd
Sensor: ColorVision, Inc. - Spyder 4
no sensor->get_sample

Works just fine in DisplayCal.

There's no documentation from ColorVision so we can't use a native driver unfortunately.

Same problem with Spyder 3 express:

$ colormgr get-sensor-reading lcd
Sensor: ColorVision, Inc. - Spyder 3
no sensor->get_sample

Ubuntu 20.04 LTS

There's no documentation from ColorVision so we can't use a native driver unfortunately.

Sorry for my lack of knowledge: Is there a workaround?
