Hi,

Should be like this: Note the structure is called "bulk_min":

        static const uint16_t bulk_min[USB_SPEED_MAX] = {
                [USB_SPEED_LOW] = 8,
                [USB_SPEED_FULL] = 8,
                [USB_SPEED_HIGH] = 512,
                [USB_SPEED_VARIABLE] = 512,
                [USB_SPEED_SUPER] = 1024,
        };
--HPS
