For what it is worth, I have same problem with indi_sx-ccd (lodestar) and indi_asi_focuser (zwo eaf)

ubuntu apt-get versions.

I did an upgrade on ubuntu 18, then a dist upgrade to ubuntu 20. Then they stopped working.

Lsusb shows up both devices, kstars/ekos says they need plugging in. Connects ok from command line indisefver.

Can't see much in logs. Other than the devices are not connected.

Amd based laptop.
