Pink noise drops during Playback

I just get my CI1 and i have pink noise drops during playback.
Please HELP :frowning:

I found something.
The problem appears only when the card is connected in to a USB 3 (usb 2 compatible ) ports on my laptop. ( the left 2 usb ports on a Precision M6500 )
Now i work with no problems in to a USB 2 port. ( the right ones ) :slight_smile:
