Is USB faster than serial port?
USB allows data to travel on the average of ten times the speed of the normal parallel port. It is also faster than a serial port. The average serial port transfer rate is 150 kbps; the USB port is up to 12 Mbps. USB 2 is forty times faster, with a maximum transfer rate of 480 Mbps.
What is port problem?
Generally, there are only four possible causes for a problem with a device connected to an I/O port: The port is defective. The software is not configured properly for the port (that is, the resource allocation, speed, or protocol settings do not match). The connecting signal cable is bad.

If your hardware connection is correct, but the serial communication still cannot be established, the problem may lie in improper software settings.
When does Arduino stop sending data to serial port?

Why does Windows 10 not load virtual serial port driver?
The update may have impacted the ability of the virtual serial port drivers for certain devices to load by default. This poses a significant issue when you are trying to use these devices. First, we will investigate the use of Eltima Software’s Virtual Serial Port Driver to add Windows 10 virtual serial ports.
Why does serial communication stop after a long time?
A similar problem was described here in Serial communication stops after long periods., but no solution was suggested. Disconnecting/connecting the device solved the issue temporarily, but this can’t be a solution, as the device is supposed to be used permanently and fully automatically.
