I've upgraded to the latest INDI - it made no difference. I then moved to the nightly release do I could try the indi-sssag package. This installed fine, but the camera still doesn't seem to be detected.

Output from dmesg on plugging in the camera:
[44820.427273] usb 1-1.4.1: new high-speed USB device number 10 using dwc_otg
