https://devzone.nordicsemi.com/f/nordic-q-a/102399/compatibility-issue-with-nrf52840-usbd-hid-peripheral-on-macosHello, we encountered a system compatibility issue while using the USBD peripheral on nRF840. We are using SDK version 17.1.0 and using usbd_hid_generic to simulate the device as a keyboard, mouse, and HID device. It works perfectly on Windows and Linuxen-USTelligent Community 13Tue, 01 Aug 2023 06:38:10 GMThttps://devzone.nordicsemi.com/thread/439159?ContentTypeID=1Tue, 01 Aug 2023 06:38:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f20e7124-ce71-4e92-96f2-a9f71ed7ca2bSusheel Nuguru<p>Hi Ken,</p> <p><span>The problem is related to a &quot;SET IDLE&quot; HID-specific command. Both Windows and Linux set it to 0 and macos to non-zero. Macos is OK when the code just ignores the SET IDLE, but it gets upset with the handling offered by the SDK. I am trying to find out more how it is handled. We have not noticed in this difference in behavior and expectations from MacOS but the patch seems to fix the issue.</span></p> <p><span></span></p> [quote user=""]However, this is clearly not a suitable long-term solution, even though it temporarily resolves the issue.[/quote] <p>May I ask why this cannot be a long-term solution?&nbsp; I also think that the development team has fully moved to support nRF Connect SDK. So if you are still in the prototyping phase, I am obliged to recommend you to consider moving to nRF Connect SDK.</p><div style="clear:both;"></div>
