NVIDIA Jetson TK1 Enable USB 3.0 under LT4 21.1

Linux for Tegra (LT4) uses UBoot as its bootloader, replacing fastboot. In order to enable the full size USB port as 3.0, you can change the boot configuration file on the Jetson.

The boot configuration file is located here:

/boot/extlinux/extlinux.conf

There are several example configuration files in that directory which define how to boot from different devices.

The switch to change is: usb_port_owner_info=2 #USB 3.0

There are two usb_port_owner_info=0 specifications in extlinux.conf, one is extra. Only the last assignment will be used. You may delete one of the specifications, as I've shown in the following example.

A new example config file with USB 3.0 enabled:
