I have been trying to calibrate my Dell 2413 with the i1 Display using the Dell Ultrasharp Calibration Solution (DUCS).

It happens that the process always fails to start at Step 1  (setting the optimum contrast, I think). The following message is displayed:

"Could not set the display preset (CAL1 or CAL2). Error communicating with the display. Please verify the USB connection. Power cycle the display, restart the application and try again".

I have tried to connect the i1 Display both to monitor (side ports and bottom ports) and to the desktop.

I am running windows 7 Home Premium and the version of the DUCS is 1.5.10.

This is really critical for me as this is my main monitor for photography. Your help is greatly appreciated!!! 

Thanks,
