If there is no separate power supply the usb plug must be used in order to provide power for the speakers, but whether the analogue cable must be plugged in or not will depend on the internal construction and specification of the speakers. I suggest you initially use the usb and if there is no sound and no on-screen instructions, plug in the analogue line. If there is a separate power supply the speakers are probably and either/or design.

what is 'dragging'? most likely dirty contact on the plug from computer to the speakers.

Windows has a troubleshooter for the audio system in most computers. Get the "fix" here: https://support.microsoft.com/en-us/help/4026994/windows-fix-sound-problems Good luck!
