Same thing with a tiny example using hidraw (https://github.com/wulf7/iichid)
like this:

        int fd = open("/dev/hidraw1", O_RDWR);
        unsigned char usb_buf[65] = {0};
        memset(usb_buf, 0x00, sizeof(usb_buf));

        usb_buf[0x00]   = 0xEC;
        usb_buf[0x01]   = 0x82;

        fprintf(stderr, "wr %ld\n", write(fd, usb_buf, 65));
        fprintf(stderr, "rd %ld\n", read(fd, usb_buf, 65));
