We are using a USB camera (VID_174f&PID_1734) on an iMX6 board. The camera is connected to iMX6 through a USB hub (USB2517). It works fine in Android, and the following debug messages are output in Android,

root@android:/ # usb 2-1.3: new high speed USB device number 7 using fsl-ehci
uvcvideo: Found UVC 1.00 device Front Camera (174f:1734)
input: Front Camera as /devices/platform/fsl-ehci.1/usb2/2-1/2-1.3/2-1.3:1.0/input/input9

Start a simple camera test application, the camera video is displayed on screen.

If we program a QNX6.6 image to the board and run the following commands, error messages are output repeatedly.
# ln -Psf /usr/lib/libcapture-usb-uvc.so /usr/lib/libcapture.so.1

Error messages are as follow,

Other USB devices can work normally on the board (e.g. USB LAN, USB storage devices).

I also tested the camera using QNX6.5 image, and run vcapture-test command. But I got the same errors.

What else shall I do to make it work?

Thanks.
