- **hcpriv** 主机控制器驱动私有成员
- **hport** 当前 urb 使用的 hport
- **ep** 当前 urb 使用的 ep
- **data_toggle** 当前 data toggle
- **interval** urb 传输间隔，单位 us，如果 interval 大于 1000us，则需要使用软件定时器来维护
- **setup** setup 请求缓冲区，端点0使用
- **transfer_buffer** 传输的数据缓冲区
- **transfer_buffer_length** 传输长度

.. note::
这里的 `USBH_GET_URB_INTERVAL` 是一个宏定义，用于根据 binterval 计算 URB 的传输间隔时间, 单位是 us，而定时器最低是 ms ，因此需要除以 1000。对于小于等于 1ms 的不需要使用定时器。
