We are using Tegra-Jetson TK1 processor with Ubuntu 16.04 and Grinch kernel 21.5. In order to activate USB 3.0 on it, the following steps were performed:
- In “/boot/extlinux/extlinux.conf” file “usb_port_owner_info=0” was changed to “usb_port_owner_info=2”
- “usbcore.usbfs_memory_mb=1000” was added to the end of line
- System was rebooted
When the system was up, the USB port couldn’t detect any hardware device that was connected to it. Even if step 2 was not performed, same observation was made. A similar procedure is also outlined http://elinux.org/Jetson/Cameras and on other posts on this forum as well.
Any quick help in this regard will be greatly appreciated.
