I am trying to control Pt Grey Flea3 USB3 cameras. Mostly these have been excellent, but I have come unstuck trying to access certain trigger modes. THe trigger modes that Pt Grey claims are accessible, do not appear to be available as attributes, so I tried accessing registers directly. Turns out I can read registers (in steps of 4) at offsets up to 20Ch, but after that I consistently get the same (rather unhelpful) error message "Unknown USB3 Vision error" (-1074360261 xBFF6903B). This maximum offset is well shy of anything interesting in the registers. I can revert the drivers back so I can use the native FlyCap software and this does allow me to access the registers at the offsets I expect (e.g. 803h). I have seen similar posts to this problem, but don't see anything directly related. Anyone got any ideas?

Hi bostonscot,
What version of LabVIEW and NI-IMAQdx do you have on your machine? Would it be possible for me to receive a screenshot of the error message you are receiving?
How are you configuring the IMAQdx Read Register VIs? Would it be possible to receive a screenshot or VI snippet of the code where the reading from the register is taking place?

Was this resolved? I"m in the process of going down the same road.
Need to access trigger functions on Gige Flea3 camera.
Thanks,
Jim

I am fairly sure the error turned out in the end to be a documentation problem on the Pt Grey side. I think the specific camera I had actually didn't have the trigger mode that they claimed it had in the manual. Sorry I can't be of more help!
