The CH340 USB-to-serial converter is encountering substantial delays in data visualization.

The screenshot above shows data being sent by a serial port assistant. Although there is data, it is displayed very slowly and requires a long wait. Sometimes, it is even impossible to wait for the data to be displayed.

My question is that the delay in displaying the data is too large. Can the USB protocol filtering be placed on an FPGA for processing? This way, the display speed will be much faster and there will be no lagging.
