I have several Orange Pi PC boards from different issues
I made an image of Ubuntu Trusty with application,which use video 4 linux
Boards from one issue run this image successfully.
Boards from other issue - can not access /dev/video0 dtcfbse of device is busy.
fkso, mu USB camera has additional HID device, which behaves same manner
synchronously

Does work on boards, which succed on video4linux
lsusb reports, that device is connected.

Is there any ideas why USB do not function on some boards?
