自己修改dir 615H1 支持usb 修改固件大小

/home/safedebug/openwrt/target/linux/ramips/dtsDIR-615-H1.dts增加以下两句ehci@101c0000 {status = "okay";};ohci@101c1000 {status = "okay";};执行make menuconfig ，添加USB相关支持Kernel modules —> USB Support —> <*> kmod-usb-core.Kernel modules —> USB Support —> <*> kmod-usb-ohci.Kernel modules —> USB Support —> <*> kmod-usb-uhci.Kernel modules —> USB Support —> <*> kmod-usb-storage.Kernel modules —> USB Support —> <*> kmod-usb-storage-extras.Kernel modules —> USB Support —> <*> kmod-usb2.添加SCSI支持Kernel modules —> Block Devices —> <*>kmod-scsi-core添加USB挂载Base system —> <*>block-mount添加自动挂载工具Utilities —> Filesystem —> <*> badblocks添加文件系统支持Kernel modules —> Filesystems —> <*> kmod-fs-ext4Kernel modules —> Filesystems —> <*> kmod-fs-vfatKernel modules —> Filesystems —> <*> kmod-fs-ntfs添加UTF8编码,CP437编码，ISO8859-1编码Kernel modules —> Native Language Support —> <*> kmod-nls-cp437Kernel modules —> Native Language Support —> <*> kmod-nls-iso8859-1Kernel modules —> Native Language Support —> <*> kmod-nls-utf8Utilities ---> disc ---> <*> fdisk.................................... manipulate disk partition table Utilities ---> <*> usbutils...................................
