Serial 框架当前支持 cdc acm, ftdi, cp210x, ch34x, pl2303，gsm 驱动。当前支持两种使用方式，
|

一种是使用源生 CherryUSB usbhost serial API 进行操作，另一种是基于平台封装的 API 操作，比如 rt-thread device API。，nuttx posix API。

- 纯 USB 设备 + 未启动波特率，这种情况下可以使用 `usbh_serial_cdc_write_async` 和 `usbh_serial_cdc_read_async` 进行异步收发数据。阻塞则可以用 `usbh_serial_write` ，不可以使用 `usbh_serial_read`。
|
||||
|
||||
- 纯 USB 设备 + 启动波特率，同 1，但是速率打折扣（因为多了一层 ringbuf）。此时也不可以使用 `usbh_serial_cdc_write_async` 和 `usbh_serial_cdc_read_async`。 **如果是 GSM 设备请使用第一种场景**。
