单独编译内核文件：  
1、先进入到内核源码目录下：

cd Hi3519AV100_SDK_V2.0.2.0/osdrv/opensource/kernel/linux-4.9.y

2、拷贝对应的配置文件：

cp arch/arm/configs/hi3519av100_xxxxxx_defconfig .config

可选的配置文件如下，也可自行到arch/arm/configs目录下查看

hi3519av100_amp_defconfig       
    hi3519av100_amp_nand_defconfig  
    hi3519av100_amp_emmc_defconfig  
    hi3519av100_smp_defconfig       
    hi3519av100_smp_nand_defconfig
    hi3519av100_smp_emmc_defconfig

3、编译，进入kernel configuration

make ARCH=arm CROSS_COMPILE=arm-himix200-linux- menuconfig

需选择的配置如下：

Device Drivers  --->
    	<*> Multimedia support  --->
    		[*]   Media USB Adapters  --->
    			<*>   USB Video Class (UVC)
    	<*> Sound card support  --->  
    		<*>   Advanced Linux Sound Architecture  --->  
    			[*]   USB sound devices  --->
    				<*>   USB Audio/MIDI driver
        [*] USB support  --->
        	<*>   EHCI HCD (USB 2.0) support 
        	<*>   OHCI HCD (USB 1.1) support
    		<M>   DesignWare USB3 DRD Core Support
    				DWC3 Mode Selection (Gadget only mode)  --->
    		<*>   USB Gadget Support  --->
    			<*>   USB functions configurable through configfs
    			[*]     Audio Class 1.0
    			[*]     Audio Class 2.0
    			[*]     USB Webcam function
    			<M>   USB Gadget Drivers
    			< >     Ethernet Gadget (with CDC Ethernet support)
    			<M>     Mass Storage Gadget
    			< >     Serial Gadget (with CDC ACM and CDC OBEX support)
    			<M>     Multifunction Composite Gadget
    			[*]     RNDIS + CDC Serial + Storage configuration (NEW)
    	PHY Subsystem  --->
    		<*> HISI USB3 PHY Driver
    		<*> HISI USB2 PHY Driver
    File systems  --->
    	Pseudo filesystems   --->
    		{ *} Userspace-driven configuration filesystem

按照以上配置选项配置后，保存退出

vi arch/arm/boot/dts/hi3519av100.dtsi

4、编译生成uImage

make ARCH=arm CROSS_COMPILE=arm-himix200-linux- uImage

编译通过后uImage内核文件的路径在 arch/arm/boot/，重新烧录到Hi3519中即可实现USB设备的识别。
