+ * Implementation notes:
+ *
+ * USBEndpointConfig - Configured using explicit order instead of struct member name.
+ * This is due to ChibiOS hal LLD differences, which is dependent on hardware,
+ * "USBv1" devices have `ep_buffers` and "OTGv1" have `in_multiplier`.
+ * Given `USBv1/hal_usb_lld.h` marks the field as "not currently used" this code file
+ * makes the assumption this is safe to avoid littering with preprocessor directives.
