Hello. I am using Pynq Z2 board for video process project. USB camera is the source of the project. I have customed the Petalinux for the project. The USB is work fine and lsusb command can show the USB camera device. When I change the ROOTFS to Ubuntu 16.04, there is no output from the lsusb commond. It is possible to change the Petalinux's rootfs to Ubuntu or Debian?
