I bought your board Zynqberry, this is quite nice.
However, I met a problem when we tried to use our USB camera with linux on the board. In order to use our USB camera, I need to activate UVC option in linux menuconfig, but after did it, our USB bus seemed to be hung up.

I got a following message from lsusb command 
unable to initialize libusb: -99

kernel menuconfig option is
Kernel
  Device Drivers
    Multimedia support
      media USB Adapters
        USB Video Class(UVC)
          UVC input events device support

My linux kernel is linux-xlnx: official linux kernel from Xilinx, linux kernel version "4.6".

I found a information which someone can use UVC module on Zybo(degilent).
It means there is a possibility the problem depending on the board specification.
Please teach me an information or solution about something like this problem.
If you guys need more information, of course ask me.

Hello,

looks like it fixed in Petalinux 2017.1. I enable this driver and see no libusb error message.
