## Description:
More fixes flagged by pylint 2 that don't hurt to have before the actual pylint 2 upgrade (which I'll submit soon).
## Checklist:
- [ ] The code change is tested and works locally.
- [x] Local tests pass with `tox`. **Your PR cannot be merged unless tests pass**
* SCSGATE: Actually cycle through all devices to register
Modify _activate_next_device function to actually cycle through self-devices_to_register instead of simply checking whether there are any and onl registering one
* Deleted extra white lines
