I have a Galaxy Note 3 (SM-900V) running Android 4.4.2 .I have installed the latest driver and Kies 3 versions from Samsung.
My PC runs Windows 7 Home Premium SP 1 on a Pentium (R) 3.4 GHz CPU 32-bit with 4 G RAM
When I try to transfer files to/from the PC/phone, or even access the phone from the PC to see the folder tree, I get the results below. I have checked the USB cables and ports; the problem is not in the physical connection.
This same phone seems to connect fine with Windows 8.1 on another machine, without using Kies. (Please don’t suggest that I install Windows 8 on this machine as Win 8 is another wonderful Microsoft product that wish I didn't have.)
Any other suggestions will be welcome as I have run out of things to try short of resetting the phone which has always struck me a burning down your house to get rid of mice.
