Hello,
Sorry to hear about your issue. I am a developer at NI who works on driver software for USB3 Vision cameras. I have seen a similar problem with a few other cameras (see this post and this post), so I have an idea of what could possibly be happening.
Long story short, NI software resets the USB endpoints on the camera to ensure it's in a good state before trying to communicate with it. On the control channel endpoint in particular (which is used for communication like reading/writing camera attributes), I have observed that in many cases the vendor software does not do this step, but we do. Sometimes, especially if it hasn't been tested by the vendor, the camera does not correctly handle this command to reset the control channel endpoint on the camera. I am guessing that your camera does not respond well to when we reset the control endpoint when we try to open a session to the camera. Anecdotally I've seen more issues with this with Win 8+.
You can determine if my guess is correct by disabling this behavior via registry key***:
- Go to HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->services->niimaqdxk->Parameters
- Add a new DWORD (32-bit) Value called U3V_DisableEndpointStall
- Modify the data to have a value of 1
- Reboot
- Try again in MAX
Making that registry key change means that we won't do endpoint stalling on any endpoint (the image streaming endpoint for example... more than just the communication on the control endpoint). Since the stalling is used as more of a failsafe, everything should still work file with that change. However, it may impact the driver's ability to recover from error. Ideally if this is the issue, we'd want the camera vendor to provide a firmware update that resolves the problem and then you could re-enable the registry key.
Please let me know if this is the issue, as we will want to reach out to the camera vendor and let them know that the camera isn't properly handling that specific command. Because we've seen this issue across several cameras, I'm working on potentially making a change on our end as well to try to avoid getting into this situation. I'm also communicating with the USB3 Vision standards committee about how to ensure cameras properly handle this use case in the future.
Please let me know if you have any more questions, and if you can try out that registry key to see if this is indeed the problem you're experiencing.
