Aha! `glasgow` does appear to see my hardware. It's just aborting for some other reason before it prints out the list. If I use the verbose option:
```
mblair@warpcore ~/Glasgow % glasgow -v list
D: g.device.hardware: found revC3 device with serial C3-20240518T200809Z
D: g.device.hardware: found revC3 device with serial C3-20240519T143424Z
zsh: abort      glasgow -v list
```
