Not sure about your question. I'm just re-adding the deleted code in
the last commit on the affected kernel patch:
https://github.com/lede-project/source/commit/f036956e1f6a38bfc4e678adf404f3a717ceaed8#diff-0928a7bd0f08843e69824f86d7a82782L35
I assume the only one important parameter here is " .otg_cap
= 2, "
Which is causing the danube boards don't initialize the USB port correctly.
Related bug https://bugs.lede-project.org/index.php?do=details&task_id=351&opened=11&status[0]=
As Mohammed Berdai commented in the last post the ARV7518PW doesn't
detect anything on the usb port. Not sure if all danube boards are
affected. The patch solves the problem.
Regards.
