Connect device button not working

[mariobehling]

Clicking the connect device button does not open the option to connect the hardware.

Expected:

• Introductory text with option to connect device should be visible
• Device option, e.g. V5, V6 should be visible with basic guide how to identify the hardware
• Option to connect device via USB or Bluetooth should be available

@mariobehling There's an option to open the Connect Device screen in the navigation drawer. I'll link the screen to the button.
