The WT4 Setup utility wants me to go to the Setup Menu and select USB to make sure the camera is set for MTP/PTP. The D3s does not have a USB option in the Setup Menu. The User's guide does not list one either. The D3 manual does list one.
The best I can tell the D3s is by default in the MTP/PTP mode so you really don't need the Menu Item.
I have installed the latest WT4 Setup Utility and and Thumbnail utility.
Wrote up a problem report from the Nikon Support web page but so far no communication or resolution. I can't find any other way to report the problem. This pro gear so I assumed it would be worked on immediately.
Hoping you kind folks can help. Thanks larry
