The issue with locating the expected interface and endpoint descriptors arises because `configDesc` (USB_CONFIG_DESCRIPTOR) and `IfDesc` (USB_INTERFACE_DESCRIPTOR) are incremented by structure size rather than by actual descriptor length. Specifically: - `configDesc` should be incremented by its actual length. - `IfDesc` should be incremented by its actual length. This incorrect increment causes misalignment, preventing access to the subsequent interface and endpoint descriptors. [Suggested Solution] Update the code to increment the pointers by the actual descriptor lengths, ensuring proper access to all descriptors in the USB configuration.
