I have set&nbsp;USB_OTG_FSM in kernel, but there is no entry for&nbsp;/sys/kernel/debug/ci_hdrc.0/role even though /sys/kernel/debug exists.</P><P>How to make&nbsp;/sys/kernel/debug/ci_hdrc.0/role available? Is there another way to detect current OTG is in host or gadget mode?</P><P>Regards,</P><P>Winston</P> Fri, 01 Apr 2022 18:31:15 GMT https://community.nxp.com/t5/i-MX-Processors/sys-kernel-debug-ci-hdrc-0-role-does-not-exist/m-p/1437801#M188899 yangao 2022-04-01T18:31:15Z https://community.nxp.com/t5/i-MX-Processors/sys-kernel-debug-ci-hdrc-0-role-does-not-exist/m-p/1437830#M188900 <P>Figured out: Need to enable&nbsp;USB_CHIPIDEA_DEBUG to get the entry.</P><P>Regards,</P><P>Yan</P> Fri, 01 Apr 2022 21:05:03 GMT https://community.nxp.com/t5/i-MX-Processors/sys-kernel-debug-ci-hdrc-0-role-does-not-exist/m-p/1437830#M188900 yangao 2022-04-01T21:05:03Z
