This tutorial of Robo India explains how to install driver of CH340 USB to serial converter.

With the advantage of USB port, users have the capability to utilize the peripheral with serial port interface in an easy-to-use environment such as plug and play & hot swap function. This single chip is designed for ideal connections to Cellular Phone, Digital Camera, Modems or ISDN terminal adapters with over 1Mbps data transfer rate.
This direct connect USB TTL adapter works with Windows 10 and earlier or Mac OS 10 X and Linux. Serial UART cable and its 6-pin TTL connector as a regular serial device connection while the FTDI chip handles USB protocol.

Ans: USB-Serial devices support LVTTL IO levels for Inputs only. CMOS IO level is supported for both Inputs and Outputs. Do USB-Serial devices require external 1.5K pull up resistor on USBDP line? Ans: No, USB-Serial devices don't require external 1.5K pull up resistor on USBDP line. The pull-up resistor is integrated inside the chip.
