I'm eyeing a great deal on a Dell Visor but the original owner has trouble with error 7-14. I did some googling thinking maybe I can fix the error yet noone could decisively tell me how to fix it.

Regarding WMR visors and specifically the Dell Visor.

Does anyone here have any knowledge on the 7-14 error? Only thing I could find out is USB port troubles which shouldn't be an issue for me, I have 5 USB 3 ports and 1 3.1.
