My Apologies for the barrage of Posts. I was not seeing them as posted and got a bit overzealous!

I have managed to use KStars for over a year now. I am not a Linux Savi person. So any help you can give me is appreciated. I recently added an ASI294MM Pro to my AP Rig. I have yet to get IndiServer to find the Camera attached to the USB3 port of the Pi4 I am using. I also use an ASI120MM as a guide camera. IndiServer has no problem finding that Camera, even when its plugged into the HUB of the ASI294MM Pro. So the USB3 Port of the ASI294MM is working. Pi4 is running: "Linux raspberrypi 4.19.75-v7l+ #1270 SMP Tue Sep 24 18:51:41 BST 2019 armv7l GNU/Linux"

Here is what I get from Ekos when I profile two ASI Cameras (the ASI120MM and the ASI294MM) and a Telescope Simulator:

2020-10-16T16:00:45 Unable to establish remote devices:

2020-10-16T16:00:30 INDI services started. Connection to remote INDI server is successful. Waiting for devices...

This is how I am launching IndiServer : "indiserver -v indi_simulator_telescope indi_asi_ccd"

This method has always worked for me (without the Telescope Simulator of course), even when I had two USB2 ASI Cameras attached to the Pi4 / one for imaging and one for guiding. I was convinced I did not have the most recent "indi-asi" driver installed, but I have not seen any posts providing this as a remedy. One thread suggested running "sudo apt-get install indi-asi", but with this change, even the ASI120MM would no longer load. I just got :"Child process 1944 died" and "client shut down."

When I tried "sudo apt-get dist-update", I got "Invalid operation dist-update".

I could use some help with two things (for now):

1) Where can I find an actual List of Cameras supported by INDI / Either from ASI or on the INDI pages / I need to check that the ASI294MM Pro is supported
2) How do I make sure the "Latest" ASI drivers are available to my Pi4 when I run the IndiServer / I am using an install from over a year ago

My Linux is very basic, so please include Details...

Thanks again if anyone can help...
