libusb error -6: LIBUSB_ERROR_BUSY

I am using Ubuntu 14.04. I have installed libfreenect2. But, when I run ./Protonect, I get the following error:

[Freenect2Impl] enumerating devices...
[Freenect2Impl] 10 usb devices connected

I have changed the permission of the usb according to https://github.com/code-iai/iai_kinect2/blob/master/README.md .

I am sorry. The issue is solved. I had to first identify my USB3.0 port. Cheers.
