Reply With QuoteCheck you have either Mass Storage Mode (MSM) or Media Transfer Protocol (MTP) selected in Settings>System>Interface. If interface setting is correct and it should be after resetting the device back to factory default settings by a 'hard reset', try the following in order:
(1) Ensure the computer has [Only registered and activated users can see links. ] loaded, if unsure how to check just download latest and install anyway.
(2) Use only a Windows desktop PC and directly connect to a rear USB2 port, avoid front ports and USB3 ports, definitely no hubs.
(3) There may be a problem with the USB cable used so try several others.
(4) The device's USB socket might be damaged or corroded, check for bent pins with a magnifying glass. If dirty clean carefully and only with dedicated electrical contact cleaner.
