https://devzone.nordicsemi.com/f/nordic-q-a/126408/inquiry-regarding-nrf52833-d-d--pin-state-when-usbd-is-disabledHi Nordic Community, I am working with the nRF52833 and I have a question regarding the electrical characteristics of the dedicated USB signal pins (D+ and D-) when the USB peripheral is unused (USBD is disabled). I understand from the Product Specificationen-USTelligent Community 13Wed, 07 Jan 2026 14:24:12 GMThttps://devzone.nordicsemi.com/thread/558182?ContentTypeID=1Wed, 07 Jan 2026 14:24:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5180d4c3-aed5-43a6-bf8c-bc6fba3c940cKazi Afroza Sultana<p>It should be high impedance. You can try to run any sample from NCS which does not have USB enabled and to measure the resistance on the test points. You will get high impedance with the floating pins.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/558096?ContentTypeID=1Wed, 07 Jan 2026 07:27:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d048e88e-af39-438c-87c0-94f4442a41fdTurbo J<p>Those pins should be powered from USB VBUS line - which is at zero volts with USB disconnected.</p> <p>That would put D+ and D- into &quot;not powered&quot; state, which is different from &quot;high impedance&quot;.</p><div style="clear:both;"></div>
