Note:By default, the USB to serial port driver (pl2303) is installed in Ubuntu ). I am using ark3116, which is also the default installation.

1. # lsmod | grep usbserial
If USB serial exists, the USB-to-serial port is supported.

Yzj @ yzj-LAPTOP :~ /Minicom $ lsmod | grep usbserial
Usbserial 36264 3 ark3116

2. Plug in the USB to serial port and enter the command # dmesg | grep ttyusb0 on the terminal. If the connection is successful, the Ubuntu system has recognized the device.
