To be compatible with the previous method, add a buf between cdcacm
and serial. Because when using usbreqbuf directly as the buf of serial,
the amount of data sent may be insufficient due to the limit of the
number of reqs. For example, when the number of reqs is 4, the number
of data send through cdcacm is 5, and each data is a separate USB
packet, if the host does not read in time, resulting in blocking send.

being received. If the application always waits for 5 numbers before
performing an operation, this will cause problems.

In cdcacm, USB req buf is directly used as serial buf, so the getting
buf status operation in ioctl is different from the original serial.

Use the CDCACM as a SYSLOG output device, send message to remote proc.
If there are more than one CDCACM devices, then a device minor number
may also need to be provided. Default: 0

Data form serial framework will be written to usb reqbuf directly,
and data form cdcacm will be read form reqbuf directly.

Make sure that the cdcacm is disconnected before the usbdev gets unregistered.
Also, check if the device is connected or not in cdcuart_txempty (uart_txempty). Otherwise there may be a crash during uart_tcdrain, called in tty close path, if the usbdev unregistration happens during the loop.
This issue can be triggered by monitoring the cable connection status in one thread, sending BOARDIOC_USBDEV_DISCONNECT if the usb cable is detached. In another thread close the ttyACM.

Some USB controllers can receive or send multiple data packets then
generate one interrupt. This mechanism can reduce the number of data
copies. Extend req buf to accommodate this.

When usb is re-enumerated due to the reset signal, we need to push
the rx_pending message into the serial port buffer.
