Because there is a condition on which I don&#39;t want any PC to recognize my device as a USB HID. If I initialize the USB in Startup and uninitialize it at theen-USTelligent Community 13Sun, 18 Dec 2022 13:32:10 GMThttps://devzone.nordicsemi.com/thread/401150?ContentTypeID=1Sun, 18 Dec 2022 13:32:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9eb51d92-8b3c-40e4-9529-05ac8a1dd86dVahidreza<p>Sorry for the late answer. You might have solved your issue but I just wanted to say that for implementing the dynamic initialization, it looks like you need to reset the microcontroller.&nbsp;<br /><br />If I wanted to implement&nbsp;the dynamic initialization and did not mind microcontroller reset, I would use the fds functions to save the desired mode and check it on startup.<br />Anytime I wanted to reinitialize the USBD in a different way (different HID config&nbsp;for instance) I would save the desired initialization flag in flash and reset the microcontroller by software.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/395014?ContentTypeID=1Thu, 10 Nov 2022 01:10:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d8845f40-1f90-48d2-bdb4-290a515e89bbyoyou<p>I have the same question,</p> <p>i want to</p> <h1 class="name">initialize and uninitialize USBD dynamically</h1> <p>beasuse some times i start USB audio, and other time start USB uart(nRF5_SDK17\examples\peripheral\ADC)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/394307?ContentTypeID=1Mon, 07 Nov 2022 06:50:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:968d1b24-fcdc-4af0-bc85-5eb335ecee61Vahidreza<p>I did not need to uninitialize the USB HID. app_usbd_stop() and app_usbd_disable() were enough.</p><div style="clear:both;"></div>
