How can I check the firmware version of a primesense Xtion camera?
I have a couple of these cameras which I suspect have different firmware versions. One works with NiViewer, the other doesn't. Although both are detected as connected to a usb port (I repeat the test on the same usb port). I don't want to flash firmware upgrades directly without knowing the current versions (I recently screwup another camera by just trying different firmwares). Ideally, I'm looking for some app I could run from ubuntu that can show the firmware version of the camera.
Looking at APIs, I found a getFirmwareRevision() call for the Structure SDK but I think that's for the occipital camera only. I've checked OpeneNI2 API and the most similar sounding function I've found is a call to GetFirmwareParams() but I can't see any example that refers to the firmware version, so I suspect that's for a different use.
