Jetson Dev Pack L4T r21.4 - enable USB 3.0

Has anybody enabled USB 3.0 on 21.4? If so, how did you go about doing it? I am reflashing my device and wasn’t sure if it was the same as 21.1 where you change the /boot/extlinux/extlinux.conf file and change usb_port_owner_info=0 to 2. Also, i read elsewhere that some people change the kernel before installation… Did I Miss something?

The extlinux.conf edit is correct.

Some people use the Grinch kernel which adds a lot of popular functionality, typically for things like wireless support. If you don’t have a missing driver you don’t need to worry about the kernel. If you do have a missing driver, you might just put in a pre-built Grinch kernel…or you might just compile a module in the existing kernel. Grinch has the advantage that it includes some back-ported drivers which don’t exist in the default kernel (and thus they can’t be compiled in the default kernel).

The procedure is the same for 21.4 as it is for 21.1. Change the /boot/extlinux/extlinux.conf file.

Ok, thanks.
