Plugging in FireWire / USB-based units while a computer is on is referred to as hot plugging or hot swapping. Konnekt does support hot plugging, however on certain Mac laptops hot plugging of the Konnekt is not possible. This may cause the screen to go black. In the event that this happens:
Please disconnect the Konnekt
Let your laptop go into sleep mode (close the lid of the laptop)
Open the laptop again
The screen should now be visible and you can shut down the computer in order to plug in the Konnekt. When connecting the Konnekt your computer should always be turned off or in Sleep Mode.
