When the USB device is connected, the USB system automatically detects the connection and identifies the data transfer rate it uses. USB uses the method of increasing the pull-up resistor on the d+ or D-line to identify low-speed and full-speed devices .USB supports 3 types of transfer rates: low-speed transmission of 1.5mb/s, full-speed transmission of 12mb/s, and 480mb/s transmission at high speeds.When t

Due to the widespread use of the COM protocol, many devices, although the interface changed to USB, but the internal data communication protocol is still using COM (that is, the traditional RS232 serial port protocol, the new use of TTL). Many devices use PL2302/CH340/FTDI and other chips to simulate the serial port protocol via USB, such as ARDUINO/NODEMCU, etc., using a similar mechanism.Under Windows, after you install the driver, you can find the emulated COM
