Well, that happiness was unfortunately short-lived :/
Pulled an update today (sudo apt-get update && sudo apt-get -y dist-upgrade) and now the sv305 driver crashes when I try to connect. Pretty sure the sv305 driver didn't change, but it upgraded some indi packages (my Canon DSLR started working)
I've attached the logs, and this line seems worrying
