A huge portion of the support team is currently on Christmas vacation and you may experience delayed answers. Most of the staff will be back 6 of January 2020 and you can be sure to get an answer shortly after that.

Best regards,

This is the example of USB MSC and USB HID,if you app_usbd_class_append one class of them,it works correctly.

But if you append them together it apperas "STATUS_DEVICE_DATA_ERROR"devzone.nordicsemi.com/.../usb_5F00_and_5F00_msc.zip

Could you share your project, then I can take a look at it and try to resolve the conflict I encounter.

Combining USB device classes requires usage of the IAD (interface association descriptor), which SDK16 supports (APP_USBD_DESCRIPTOR_INTERFACE_ASSOCIATION, app_usbd_descriptor_iad_t).

But that requires understanding of the USB code and is not just "combining two examples together".
