I'd make sure you have usb selected on the modi at the front of the unit and that the power cord is connected at the back.
Do you fully shut down your laptop much? or restart windows? If not, try shutting down your system/laptop, make sure modi is fully powered and then plug it in to the laptop whilst shut off, then restart and see if that works?!
Could there be an issue with that particular usb port that you are connecting the modi into? Try testing it with a thumb drive or something and see if it acts up?
Lastly, check in your device manager in the control panel and see if you have any problems with your system, usually a troubled usb port or usb device will be flagged in your control panel.
If you do have an issue in the control panel then that might mean you might need to update the device driver, try here for Schiit modi2u:
