Add usb driver and related scripts to OpenWrt

Add usb driver and related scripts to OpenWrt
Step 1: Add Kernel support

Openwrt compilation supports the USB automatic mount Function

Make menuconfig
1) Add USB support
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.

2) Add SCSI support
Kernel modules-> Block Devices-> <*> kmod-scsi-core

3) add USB mounting
Base system-> <*> block-mount

4). Add an automatic mounting tool
Utilities-> Filesystem-> <*> badblocks

5). Add File System Support
Kernel modules-> Filesystems-> kmod-fs-ext4
Kernel modules-> Filesystems-> <*> kmod-fs-vfat
Kernel modules-> Filesystems-> <*> kmod-fs-ntfs


6). Add UTF8 encoding, CP437 encoding, ISO8859-1 Encoding
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

Step 2: Enable automatic mounting

Df should be able to see the mounted USB hard disk.

Below is a boot script for the vrousb to automatically mount the USB hard disk at startup.

Vim/etc/init. d/usbdisk

Write script:

#!/bin/sh /etc/rc.common 

START=99 

STOP=10 

start() { 

mount -t ext3 -o noatime /dev/scsi/host0/bus0/target0/lun0/part1 /mnt 

} 

stop() 

{ 

sync 

umount /dev/scsi/host0/bus0/target0/lun0/part1 

}

restart() 

{ 

stop

start 

}

Add executable permissions

Chmod 755/etc/init. d/usbdisk

Add to startup directory

Ln-s/etc/init. d/usbdisk/etc/rc. d/S99usbdisk

Step 3: Hot swapping support
Automatically mount the script and create a 30-usbmount file in/etc/hotplug. d/block,#! /Bin/shCase "$ ACTION" inAdd)For I in $ (ls/dev/| grep 'sd [a-z] [1-9] ')DoMkdir-p/mnt/$ IMount-o iocharset = utf8, rw/dev/$ I/mnt/$ IIf ["$? "-Ne 0]; thenMount-o rw/dev/$ I/mnt/$ IFiDone;;Remove)MOUNT = 'mount | grep-o '/mnt/sd [a-z] [1-9]'' For I in $ MOUNT DoUmount $ IDone;;Esac
