discoveranother 0 Posted January 17, 2014 Have an Inspire DVR. The manual shows that the recordings can be backed up to USB drives. I have connected 4 working USB drives but when I select to check backup devices ready for copying, the DVR sees nothing. Strangely, if I connect the USB mouse which came with the product to the USB on the DVR there is no problem. I know it isn't the memory sticks because they all work when connected to a computer.
