Hi,

Here is some info: Running Rpi 4 4gb w/ astroberry
Camera: QHY294m
FW: QHYFW3
Guide cam: ZWO120mm
Mount: EQ6-r

Issue: It seems that I can get my camera and my guider connected properly, and they each take up a USB3 port on the pi. I have my Filter wheel connected through my QHY camera. My mount is connected through a USB2 port.

It appears that I can connect either my mount or my filter wheel (when running the QHYFW2 drivers and not the 3rd gen drivers), but not both together. I get the message Port /dev/ttyUSB0 is already used by another driver or process. When I connect my filter wheel separately to USB2, Kstars/EKOS crashes and then I can't connect either of my cameras or filter wheel, but I can still connect my mount.

I see that some people have also had this issue, but I haven't been able to resolve it. As a side note, I am pretty new to Linux and Rpi, but I can work my way around if needed.

Thanks!
