常见的USB转串口驱动有cp201x，pl2303进入kernel，配置menuconfig
#make ARCH=arm menuconfig
选中 Device Drivers > USB support > USB Serial Converter support下面的
<*> USB CP210x family of UART Bridge Controllers
<*> USB Prolific 2303 Single Port Serial Driver
重新编译内核
make ARCH=arm rk3288-evb-android-rk808-mipi.img -j8
烧录内核固件，上电运行，查看驱动是否加载成功
ls /dev/ttyUSB0
此时可以看到dev目录下出现设备节点ttyUSB0.驱动加载成功。
