D300S no live view when usb connected
I am experimenting with using my D300S on a good quality microscope using Lightroom 5’s tethered shooting abilities on a Windows 8 machine. Everything is setup correctly. LR recognizes the D300S and I can take pictures using the on-camera shutter release and remotely from LR and they show up fine in LR.
Here’s my problem. I can’t access live view when the USB cable connecting the camera to the computer is plugged into the camera. The live view button does nothing while the usb cable is plugged in. Unplug it and everything is fine. This doesn’t seem right to me. Should I not be able to get a “live view” on my computer screen? That would really help with focusing the microscope. Also, it suggests I can’t capture video while tethered to LR. Am I missing something or is LR tethering really that limited? I have the same issue whether I have a microscope adaptor or a lens connected to the camera.
I can’t seem to find clear info on the web. I found info saying that other capture software, e.g. Nikon’s Camera Control Pro 2, needs to go between the camera and LR but those sites referred to early versions of LR. I also found info suggesting that isn’t necessary with more recent versions, which is supported by the fact that recent versions of Windows are not listed as supported OS’s on the Camera Control website. I did notice, however, that Windows 8 did automatically install some kind of driver before LR would recognize my tethered D300S.
So can anyone shed light on this, please? Will live view just not work when a usb is plugged into the camera? Is this a limitation of LR5? Do I still need intermediate software? I appreciate any help you can give.

Is the problem LR or Windows 8? Does Live View work when the camera is connected to the computer with LR not running? If not, then the problem may be Windows 8 (?).
By the way, I believe there are two possible USB modes that can be set using the camera menus. Which one are you using? Have you tried both?

Thanks for the responses.
First,the D300 has two USB modes and needs to be set to ptp mode for tethering to work. The D300S, however, only uses ptp mode so that's not the problem.
As suggested I further checked connections. With a usb cable plugged into the camera but leaving the other end free, the live view button on the camera works. As soon as I attach the free end to the computer, live view no longer works.
I then installed the open source digiCamControl software which supposedly supports Windows 8 and the D300S. The live view button on the camera still doesn't work but the software has a live view control that does activate the function on the camera. Unless I'm missing something, Lightroom has no such ability.
So my 'problem' seems to be either a limitation of LR or the software/Windows combination. The 'solution' seems to be to use other tethering software, not LR.
Or perhaps my problem is ignorance. I have no experience of tethered shooting. Am I right in expecting the live view button on the camera to be functional or must it always be software controlled when tethered?

Some tethering software will accept the live view video, thus enabling you to focus using the image on the sensor. Lightroom is not one of those that will do this. It does allow you to chimp at full size directly after taking the shot and gives you exposure control from the computer. Nikon's Camera Control Pro does use the live view video. But, if there is no CCP version that will work with your current Windows version, then that will be of no use to you.
It is a limitation built into the camera that, once connected to a computer (PC shows on the top display in place of the image count), the camera will no longer allow live view to be displayed on the camera.

Thanks, Hendrik. That all makes sense in light of my experimenting. I will look more closely at other tethering software. The open source one I briefly tried seems pretty good and there appears to be quite a few other options so things should work out.

I'm not conversant with the D300s or Lightroom but I do use my D300 tethered by the USB through a programme called 'ControlMyNikon' which does give you the 'live view' image on the computer screen and allows you to adjust focus remotely, change settings and shoot.
I mention this purely as it's an option should you find your existing rig will not do it and the 'ControlMyNikon' software is an alternative to the more expensive Nikon control one.
