https://devzone.nordicsemi.com/f/nordic-q-a/91150/dk5340-config-usb-driver-vid-pid-and-revisionHello, I&#39;m using the Sample usb/CDC_ACM on the DK5340 with VSC. I can set VID=XXXX and PID=YYYY, works fine. But how can I set the REVISION=ZZZZ ? So that Windows sees the revision in the driver properties e.g. USB\VID_XXXX&amp;PID_YYYY&amp;REV_ZZZZ Thanksen-USTelligent Community 13Mon, 22 Aug 2022 06:49:14 GMThttps://devzone.nordicsemi.com/thread/382566?ContentTypeID=1Mon, 22 Aug 2022 06:49:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b044d08d-5a5e-46a0-bb4b-b1665815c939Kenneth<p>Hi,</p> <p>Looking at usb_descriptor.c I can find that in&nbsp;USBD_DEVICE_DESCR_DEFINE macro that vid, pid and bcddevice (rev) is set as:</p> <p>&nbsp; &nbsp; &nbsp; &nbsp; .idVendor = sys_cpu_to_le16((uint16_t)CONFIG_USB_DEVICE_VID),<br />&nbsp; &nbsp; &nbsp; &nbsp; .idProduct = sys_cpu_to_le16((uint16_t)CONFIG_USB_DEVICE_PID),<br />&nbsp; &nbsp; &nbsp; &nbsp; .bcdDevice = sys_cpu_to_le16(USB_BCD_DRN),</p> <p>From usb_ch9.c it looks like&nbsp;USB_BCD_DRN is set at compile time as&nbsp;</p> <p>/** USB Device release number (bcdDevice Descriptor field) */<br />#define USB_BCD_DRN &nbsp; &nbsp; (USB_DEC_TO_BCD(KERNEL_VERSION_MAJOR) &lt;&lt; 8 | \<br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;USB_DEC_TO_BCD(KERNEL_VERSION_MINOR))</p> <p>So I don&#39;t really see any other way than to either modify the&nbsp;USBD_DEVICE_DESCR_DEFINE macro with a different .bcdDevice value, alternatively you can likely&nbsp;update .bcdDevice this after calling the&nbsp;USBD_DEVICE_DESCR_DEFINE macro.</p> <p>Kenneth</p><div style="clear:both;"></div>
