CP210x USB to UART Bridge Driver problem
Sorry for the late reply.
Ok. Everything you say is true.
It was to show that it did not work properly according to the driver version.
I am developing a python application.
(Regardless of version)
And..there is no v220.127.116.110 version in the release note.(this version actually exist?)

CP210x USB to UART Bridge Driver problem on
I am having a strange problem using the CP210x USB to UART Bridge Driver.
1) Windows 10, build 1803
2) CP210x Driver version: 18.104.22.1681 (Driver Date: 2016-09-19)
3) STM32F407 MCU => PC (Serial Communication)
4) Data receiving program: Python 2.7, pyserial 3.4
5) Serial communication
In Windows 10, connect to USB and receive data using Python. (pyserial)
At first, reception is good.
After 1 minute from receiving, the data is broken as follows.
The MCU is transferring the data correctly (already check the transmit cycle, waveform with an oscilloscope)
When PC receiving data.. but it seems that the data buffer is not being filled properly for some reason.
My efforts to resolve
After read driver release note, i install newest windows 10 universal driver (v.10.1.3.2130)
i confirmed that the data was received normally after updating to the windows 10 universal driver. (received data is not broken!!!)
So it was fixed after the update.
My questions and problems
The CP210x version of my other computer is v22.214.171.1240.
It's the same windows 10 build 1803, but it works fine without errors. (I did not install anything else on Windows 10)
v126.96.36.1990 The date of this driver is 2016-03-28.
I think it's a driver problem, but I want to know the cause.
Thank you in advance.
