How to remove or modify Device

I added a device through device manager, but the configuration had a typo.
How do I remove or edit? Options are not available.

I have this problem too! I am using 4.24. How silly to not be able to edit or remove a device. Then when I try to create a new device without the typo, it says failed to add device because it shares the device identifier.

Delete your saved folder in your project directory.
