Fix virtual input device creation timeouts

This change fixes a bug where a too long device name caused a timeout
during the creation of the virtual input device. Names longer than 80
bytes where truncated.
It also adds a new check that device names must be unique. This solves
multiple problems:
- Debugging is easier as device names are logged and otherwise
  indistinguishable
- If multiple devices with the same name are created and the creation of
  one of them fails it was not possible to identify which one
