Hi,there,

I need use 3 USB cameras to capture different figure,  use IMAQdx, 

firstly,  used 2 cameras and debug them in MAX, the two are all OK,

and then, assembled the last camera, when debug in MAX again,

the last camera is OK, and the 2 cameras OK before are error and error messages are:

error 1:0xBFF6900F, Attribute not supported by the camera.

error 2:0x80040217,Andetermined error code has been encountered,please note the error code and contact NI....

 Anyone knows how to solve it? thanks.

That error code sounds like you are using DirectShow cameras. What cameras are you using?

[maxmius]

all USB cameras

Can you take a screen shot of the attributes and post it?

If the cameras are all the same, and all work on their own; check/adjust your resolution, frame rate and bandwidth settings.  The addition of the third camera may be pushing your system over the available limit.
