Hi, I couldn't figure out how to reply to your private message so I will do what I can for you in this thread. Having trouble with my previous D4 and networking issues, I became a master of the WT-5. What is your trouble? From what I see from your post, it looks like you are unable to tether. LR does not support D4 tethering yet. You can only do it in Camera Control 2. Disregard the message about the USB settings as yours surely is setup properly. The D4 is not recognized as a simple "storage device" by any computer. The images must be extracted through a program or extracted through a card reader. There is kind of a workaround for the tethering issue in LR. That is to setup a FTP server and have LR monitor the folder which your images are uploaded via the FTP server. If there is anything else you would like to know about your rig, just reply here and I'll monitor the thread.
