Hello,

Thanks for your reports.

If you take a look at the driver's code, there is only one difference between the pro and the non pro : pulse guiding functions are disabled/enabled.
These issues are certainly related to RPi4 USB 3.0 / SV305 USB 3.0

Has somebody tried to plug the camera on a powered USB 2.0 only hub ?
My sample SV305 works well in USB 3.0 on amd64 if I don't change the settings to much. I will try to force it to USB 2.0 on my old laptop, and see what I get.

Is there somebody here using the Pro on an USB 2.0 RPi3 ?

Best regards,

Thx8411
