Hi,
I updated my RPi 4 to latest version of astroberry v2.0.4 today and been trying to connect my main ASI224mc and ASI120mm mini guide cameras in Ekos. When I connect both the cameras on the USB2 ports only one of them i.e. ASI120mm connects. If I connect the ASI224mc on the USB3 and ASI120mm to USB2 again its only the ASI120 that connects.But if I connect both on the RPi USB3 ports it connects successfully. I have tried with the ZWO CCD driver and using a combination of ZWO Camera 1, ZWO Camera 2 drivers. In both cases the behaviour is the same.It works fine on my Linux Mint laptop using direct connection to the cameras even though the USB ports are USB2 only. Both RPi and Linux are running Kstars 3.5.5 stable.
Any ideas what is the cause of this?
