First let me say that I am not a USB expert!

The limitation is on HW but not SW. there is no OTG USB controller in this chip. see datasheet:</P><P><span class="lia-inline-image-display-wrapper" image-alt="pastedImage_1.png"><img src="https://community.nxp.com/t5/image/serverpage/image-id/93656i614A60F898D56CF8/image-size/large?v=v2&amp;px=999" role="button" title="pastedImage_1.png" alt="pastedImage_1.png" /></span></P><P></P><P><BR />Have a great day,<BR />Jun Zhang</P><P></P><P>-------------------------------------------------------------------------------<BR />Note:<BR />- If this post answers your question, please click the "Mark Correct" button.
