OSVR Control does not detect the HDK

[dabigloosa]

I am not sure what this is as I also talking to OSVR Support and also raised a Ticket with Razer. The HMD suddenly is now showing any picture, it just sits there black. I am not in direct mode as I can see the HMD in Windows as an extended display. However, also the OSVR Control does not seem to find the HMD as it just sits there with the circle and not finding anything. What could that be? Any other ways to "find" the HMD and check if this is working somehow? I saw output before on the HMD and OSVR Control did see the HMD and updated it also.

Did this happen after trying to upgrade the latest version of the firmware? I believe the problem that you're experiencing might be related to either an incomplete upgrade or some registers on the EDID table of the HDMI receiver being corrupted.

To verify if the upgrade worked correctly, please make sure you see an "OSVR Com port device" in your device manager when you connect the HMD.. If that's the case, then just re-run the firmware upgrade, else contact support and they should be able to help you recover if the unit is stuck in bootloader mode to complete the upgrade process.

I don't really know where it has to say "OSVR Com port device" I think you mean under the ports tab, right? in that case I don't see one. for the rest my OSVR is recognized under monitors and the audio...

It looks firmware has a bug about USB(@HDK ver. 1.4). It ignores "USB unpluged or bus reset"(So, When USB repluged, it denies new address). Try unplug power. Then, replug it.

Already tried that it seems that when I try to install the com port device I get error code 10 which is a Windows error, but I don't know how to fix it I did reset my PC 7 times now hoping it would work again. But it doesn't...

Just an Update here after a while. The HDK was replaced, this now is no issue anymore. The HDK is detected ok now. However, there is an issue with either the Windows Insider Preview now, or the second HDK has problems or the IR cam, as I can not calibrate now. Cam does see the IR diodes, but does not assign "numbers" to them. Seems something is broke (again). I was not able to use the HMD for ANYTHING. So there is still a long road to go until you can just plug it in, start the server and just give it a go. For now I have wrapped up the HMD and placed it back in the box. I would have returned it and asked for a refund, but unfortunately the warranty only lasts for 30 Days, which are over now for the second HDK.

This reddit thread describes an issue that definitely is worth more than a look especially so if faceplate has been removed from hmd at all. https://www.reddit.com/r/OSVR/comments/4zrha0/osvr_screen_black/

One of the lugs for faceplate fixing screw interferes with a connector on mainboard when removing/replacing faceplate.
