驱动实际上linux2.6 内核已经自带了。
插上usb线后用dmesg ｜ grep usb 查看输出
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usb usb1: configuration #1 chosen from 1 choice
usb usb2: configuration #1 chosen from 1 choice
usb usb3: configuration #1 chosen from 1 choice
usb 2-2: new full speed USB device using uhci_hcd and address 2
usb 2-2: configuration #1 chosen from 1 choice
usb usb4: configuration #1 chosen from 1 choice
usbcore: registered new driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
usbcore: registered new driver usbserial_generic
drivers/usb/serial/usb-serial.c: USB Serial Driver core
drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303
usb 2-2: pl2303 converter now attached to ttyUSB0
usbcore: registered new driver pl2303
drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver

看到usb-serial.c执行，说明linux2.6内核下默认有usb转串口的驱动。
倒数第四行，说明芯片是pl2303
倒数第三行，说明usb转串口被挂载到了ttyUSB0。

配置minicom
设置串口为/dev/ttyUSB0, 保存。重启设备，即可看到串口输入信息。
