Hi,

On my SABRE board (i.MX6 Quad), I used a USB hub to connect to J505 USB port. When I connected the UVC Camera (Creative Live! Cam Sync HD VF0770) to the USB hub, I got the following message:

usb 1-1.4: new high speed USB device number 6 using fsl-ehci

usb 1-1.4: device v041e p4095 is not supported

But I couldn't see the message indicating the camera is found like others see:

uvcvideo: Found UVC 1.00 device Venus USB2.0 Camera (0ac8:3450)

input: Venus USB2.0 Camera as /devices/platform/fsl-ehci.0/usb1/1-1/1-1:1.0/input/input5

And I couldn't find /dev/video0 either. I don't think it's because of the message "usb 1-1.4: device v041e p4095 is not supported", because first, my mouse is reporting this message too and it's working, second, I saw others online reporting this message on camera, but as long as uvcvideo found the camera, it's fine.

The camera is fully functioning on ubuntu (under VMware). on i.MX6, I did the following checks:

root@freescale /$ zcat /proc/config.gz | grep V4L

CONFIG_VIDEO_V4L2_COMMON=y

CONFIG_VIDEO_V4L2=y

# MXC Camera/V4L2 PRP Features support

CONFIG_V4L_USB_DRIVERS=y

# CONFIG_V4L_MEM2MEM_DRIVERS is not set

root@freescale /$ zcat /proc/config.gz | grep USB_VIDEO_CLASS

CONFIG_USB_VIDEO_CLASS=m

CONFIG_USB_VIDEO_CLASS_INPUT_EVDEV=y

It's pretty much the same as on ubuntu.

Can anybody tell me what's wrong?

Thanks,

Jason
