USB to serial port configuration in Linux

The USB-to-serial port configuration in Linux was completed for half a day today, and finally the USB-to-serial port under RHEL 6.2 was completed. 1) if you are not sure what chip is used when you connect the USB to the serial port, you can perform hot swapping and view the dmesg information:
Usb 1-5.1: new full speed USB device using ehci_hcd and address 4usb 1-5.1: New USB device found, idVendor = 0557, idProduct = 2008usb 1-5.1: New USB device strings: mfr = 1, Product = 2, SerialNumber = 0usb 1-5.1: Product: USB-Serial Controllerusb 1-5.1: Manufacturer: Prolific Technology Inc. usb 1-5.1: configuration #1 chosen from 1 choiceusbcore: registered new interface driver usbserialUSB Serial support Registered for genericusbcore: registered new interface driver connector: USB Serial Driver core www.2cto.com USB Serial support registered for pl2303pl2303 1-5.1: 1.0: pl2303 converter detectedusb 1-5.1: pl2303 converter now attached to ttyUSB0usbcore: registered new interface driver pl2303pl2303: Prolific PL2303 USB to serial adaptor driver can be seen using the pl2303 chip, and then the ttyUSB0 device is automatically generated. If this device is not generated, you need to create the device by yourself through mknod; www.2cto.com 2) then it is very easy. The kernel seems to automatically load the following modules: [root @ host2 ~] # Lsmod | grep pl2303 17792 1 usbserial 38620 3 pl2303 with these two modules, ttyUSB0 can be driven; 3) Use minicom-s for configuration; this is easy, tutorials are available online.
