I have also faced the same issue with my system while I trying to connect my camera with my PC through the USB. It is really a matter of concern and quite a difficult to solve, so I will suggest to visit Arlo Camera Offline for the entire suggestions.
This is one of he most common errors that we all more or less face, and it is quite a difficult job to get resolved it. So, I will suggest to visit Fix Epson Printer Communication Error on Mac if anyone face the same issue with MAC.
I am also looking for this as I am unable to connect the printer with my computer and it is showing Canon error code 801. I have also searched on the Internet and there I got to know that the antivirus is actually disabling the access.
