Hi.
I have 2 usb cameras which work fine when plugged into seperate USB busses. I want to use multiple cameras with a usb hub and to lower the frame rate. The default frame rate is 30 fps and the cameras work fine independantly at this speed. To try to get 2 devices working I have opened 2 NI-MAX windows. I have changed the video mode to 288x288 YUY2 7.5 fps. This is a substantial reduction. I do the same for the other camera in the other NI-MAX window but I get a timeout error 0xBFF6901B when trying to preview the second camera. Surely this should be able to handle both devices with the lowered speed.
Is this possible or does the bus not allow more than one camera device?
Thanks,
Mark.
