USB problems

Symptom: The USB connectors cannot be accessed.

Actions:

Ensure that the USB cable is securely connected to the USB connector and to the USB device. If the USB device has its own power cord, ensure that it is attached to a properly grounded electrical outlet.

If the USB device has its own On/Off switch, ensure that it is in the On position.

If the USB device has an Online switch, ensure that it is in the Online position.
