自己修改dir 615H1 支持usb 修改固件大小

/home/safedebug/openwrt/target/linux/ramips/dts

DIR-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-ext4
Kernel modules —> Filesystems —> <*> kmod-fs-vfat
Kernel modules —> Filesystems —> <*> kmod-fs-ntfs

添加UTF8编码,CP437编码，ISO8859-1编码
Kernel modules —> Native Language Support —> <*> kmod-nls-cp437
Kernel modules —> Native Language Support —> <*> kmod-nls-iso8859-1
Kernel modules —> Native Language Support —> <*> kmod-nls-utf8
Utilities ---> disc ---> <*> fdisk.................................... manipulate disk partition table Utilities ---> <*> usbutils................................... USB devices listing utilities

重新编译就行了。
