[Android 4.4.2] Preview and video recording issue on USB camera

[charleshuang]

Hi NXP

I test USB camera (logitech webcam) in imx6 sabresd demo board (Android 4.4.2).

I used usb-hub to connect to OTG port. 

Because I need to connect usb camera ,usb mouse and keyboard. 

When I open camera apk and preview it, the picture is not correctly.

Please refer the attachment file.

VID_20160908_090232.3gpp is recording video.

pass.jpg is correct picture.

error.jpg is not correct picture.

Do you have any advice?

Are you having this problem only when you use the USB Hub?, or is it independent of it?

Hi SerigioSolis

Yes, this problem only when I  use the USB HUB.  Because our application need to connect usb camera , usb mouse and usb keyboard in platform.
