https://www.nikonimgsupport.com/na/NSG_article?articleNo=000066550&configured=1&lang=en_SGIn it they are saying that an UC-E4 cable is required.
The UC-E4 is used by these series of cameras:
D100, D200, D300, D300s, D700, D2-Series, D3-series; and
D40, D40X, D50, D60, D70/D70s, D80, D90, D3000, D3100, D7000.
In looking at my D700, the plug that goes into the camera is a standard Mini-USB B, with a regular sized USB-A plug on the other end.
Such cables are still easily sourced from computer shops as well as the official Nikon UC-E4.
