com.android.usbserial.driver.SerialTimeoutException: Error writing 64 bytes at offset 0 of total 64, rc=-1 #474

After about 20 hours of continuous operation, the communication was suddenly interrupted and the following error was sent again: “com.android.usbserial.driver.SerialTimeoutException: Error writing 64 bytes at offset 0 of total 64, rc=-1”，

Serial port chip information is as follows: “prolificSerialDriver_vid=1659&pid=9155”.

When an error occurs, the usb device is connected again and cannot be connected. Finally, the USB device is restored to normal
