vyasvenkat1996 — Fri, 06 Mar 2020 10:41:54 GMT

As i am using imx6 board as peripheral and mounting of gadgetFS also done. But i am unable to see usb port at host side . by command lsusb.

After mounting gadgetFS logs i'm getting is -

root@imx6ull14x14evk:~# mkdir /dev/gadget
root@imx6ull14x14evk:~# mount -t gadgetfs gadgetfs /dev/gadget

root@imx6ull14x14evk:~# cd /dev/gadget/
root@imx6ull14x14evk:/dev/gadget# ls
2184000.usb

So what changes and what things i have to update to get usb port at host . and i'm using imx6ull board as peripheral.

Did you load gadgetfs.ko by "insmod gadgetfs.ko" ?

or compilied it into linux kernel?

You can also refer to the link, very similar to your question.
